Stupidity: The case is made to be this incredibly complex locked room murder mystery, but it is so simply because nobody did a routine check of the phone records of the suspects / one of the victims (if not of the cell tower of the zone). The detectives would have instantly stumbled upon a major unexplained contradiction, since an incriminating call was made.
Stupidity: An explanation is given for the reason why the bombs planted on the Gundam are not activated by remote control (they have plastic explosive in the regiment but not remote controls!), but no reason why they set the timer for the explosion to 30 minutes, way too much to be of any use in combat against the Gundam. Moreover, if the vulnerable spot of the Gundam shield were situated where it explodes at the beginning, it'd be completely useless.
Stupidity: After one of the policemen decides to jump over the railing and right into the angry mob (!), Arthur just easily sneaks by ducking under it and takes a nice stroll that will lead him through an unlocked door. Nobody in the mob he is part of decides to do the same, and you can also see that one of the policemen is turned towards him, but does not even yell at him or move. And of course, with the theater packed with the Gotham elite basically under siege by a mob and guarded by the police, the door is unlocked and unchecked. Why not.(01:02:55)
Suggested correction:The point is they were all too distracted by the tussle to notice Arthur ducking behind the barrier. No cop sees him. The angry mob is controlled by the barrier and not all that large so they haven't taken extra precautions to keep the mob at bay, yet. The door Arthur gets in is probably a fire escape and can't be locked for safety reasons.
I think that with an angry mob worth putting barriers and a big police dispatch, they'd tend to lock the door that is like a 20 feet of walk in a straight line. I mean, they have barriers in front of the stairs, but at the base of the stairs there's an unguarded, unprotected, unlocked door. It's just funny. Not even something in the back or around the corner, no; literally one step to the right of the blockade.
Stupidity: After a brawl with gunshots exploded in the cafe, and having just seen Jane pull from the backseat a huge gun, Elena is shocked that the bad guy is shooting at the car and even asks "OMG, is he shooting at us?" How does a line like that make any sense, already late in a chase with weapons involved from the beginning?(00:20:45 - 00:22:40)
Stupidity: The bad guy who spies on Bosley is visible from the very beginning of the scene, when Elena is not even inside the cafe yet. The cafe does not have many customers and the bad guy is using a loud vintage typewriter with a big mirror mounted on top (!). The Angels are portrayed as being super smart and their setup is so careful, but somehow they managed to miss something amazingly obvious. Conversely, nobody would have ever paid attention to a laptop or any silent, modern-age device perhaps with a camera or something similar, so the bad guy chose the most blatantly conspicuous accoutrement for his spying job. Try showing up to a cafe punching the keys of a big clunky typewriter and literally everyone will be looking at you.(00:18:25)
Stupidity: A huge amount of movies and TV shows would be over in 5 minutes if only the person who just uncovered a horrible secret (such as who committed a murder) and is calling the good guys about it would quickly spill out of the gist of it instead of just setting up an appointment for a later meeting when they are supposed to discuss at length their findings, and which will only turn out to be the investigation of their own murder.
Stupidity: The super powerful Romulan commandos (no doubt with the help from the higher-ups infiltrated in the Federation) managed to touch up the footage of the fight in the roof so to remove every trace of the Romulan agents present. But Picard has been running, dodging blasts, ducking, and is knocked back by a huge explosion caught on camera and not deleted; we see it in this episode and it is unequivocally not caused by him. What is the point of going through subtly deleting every trace of the aggressors when it is transparent that something real happened and it's not all Picard's imagination? And the police simply take Picard back home from San Francisco to France without questioning him, not caring about investigating the explosion in the heart of the city involving a famous Admiral battling invisible enemies. If the conspiracy can erase anyone from the tape, why not erase Picard too, or the explosion and explain how he ended up K.O.'d differently?
Stupidity: Batwoman not only drives through town the same bike as Kate, in full Batwoman garb including the cape, but at the beginning of the episode is driving to Wayne enterprises, right inside the employees entrance (clearly marked as such). Even funnier considering the fact that the series keeps referencing things such as security cameras and people taking Batwoman pictures with their phones, elements that were not a concern decades ago and that would if anything require more caution, not less. The old Adam West show with all its camp and obvious absurdities had him at least drive his car to the outskirts of town and come in and out through a secret entrance, not his home garage.(00:03:00)
Stupidity: The gun stolen by the villain was designed by Batman, according to Luke Fox, in case the wrong person got a hold of the batsuit, which is bulletproof. As shown in the previous episode, the suit has electronic devices like a defibrillator implanted inside, which are remote controlled (huge security hazards, but never mind) and has obvious weak points, like the jaw, that a skilled fighter like Batman himself could exploit. It is not an invincibility suit by any means. So Batman built a super-gun able to kill himself and stored it into a simple warehouse while having already a perfectly working prototype (so he basically keeps 2 of them around); he is obviously an idiot who built a devastating weapon that any villain can steal and use against him (or anyone with body armor and more) for no real reason, a weapon designed to kill and not disable, even, contradicting his MO judging by the rest of the arsenal.
Stupidity: The protagonist removed a blood-stained bottle from the bloodied car where the murder takes place, and this may incriminate him. To avoid being found out by the police, he disposes of it where, he unironically comments "nobody will find it." Which is...the closet of his bedroom. It works.
Stupidity: Magpie in theory has the exploding pearls as diversion for her escape, but the pearls explode all too soon and in a room that she already emptied with the false alarm. Reality is that she has to face already zero security without the pearls being a factor, the moment she presses the alarm button. That's because for some reason every single Crow armed guard went to the exit to help the guests leave (in a most unprofessional way as they further crowd up the exit standing right in the way) and nobody remained behind to remotely keep an eye on the jewels. Also of course there is no alarm whatsoever on the jewelry cases, that can be opened at will. That is a serious joke of a security, and supposedly made by professionals, former navy seals, green berets etc.
Stupidity: This is not quite 'stupidity' but rather a "movie logic", supposedly sharp deduction that is really just a wild and nonsensical guess. Zenigata knows for a fact that Fujiko is impersonating Elena because she knew right away where to get the first aid kit, while Elena hasn't been in the mountain house since her husband's death. That makes no sense; Zenigata has to assume that Elena was completely straight about that fact (if it was the treasure's hiding place as he suspected, she easily could lie), and a person can easily remember where they store their security items even after years, for a variety of reasons.
Stupidity: Spoiler. In a typical 'why didn't he do it before?' twist that kinda invalidates the rest of the movie, it turns out that the villain has had a third Will Smith clone all along, ready for deployment in Yemen and with fear and pain genetically removed, ready to blindly kill anyone, combined with so much body armor that even point blank AR-15 carbine shots barely faze...but he sent the 'prototype' he raised like a son instead, in a hoodie and baseball cap.
Stupidity: Despite the fact that the villains know exactly where Brogan is for the better part of the movie thanks to a tracer, and that they display constantly that they are able and willing to hit with bold military operations even to the point of hitting an urban area overruling law enforcement (apparently Clay has authority to do that too), Brogan is able to get undisturbed back in the US through his friend's plane. Considering he was officially marked as a rogue agent and killed 8 DIA operatives, it's hard to see how Baron's plane could ever land on American soil after a long intercontinental flight.
Stupidity: Daphne and Velma's adventure in the corridor behind the school lockers begins when they enter the theater backstage from a random door opened by a button that is lit up in the dark, effectively negating the "secret tunnel system" status. Why would anyone build a corridor with an entrance into school lockers so secret that it's invisible from the outside, and then put a button-activated entrance to it in another location, even making the button a fully lit one shining in the dark?
Stupidity: During the ghost chase montage, why would Velma look for her glasses with her hand in midair instead than on the ground? No matter how nearsighted you are, the closest wall, or obstacle, is meters away and you'll never find your glasses anywhere but the floor. She does it for a longer time than anyone would.(00:52:40)
Stupidity: Batman and Robin tore apart the umbrella looking for clues to the point of micro-analyzing the fabric and the ribs, but they did not look at all into the largest and most obvious hiding spot; the handle.
Stupidity: Whatever Batman thought he was throwing instead of the confetti bomb from the belt the Joker switched with his own, the Joker had already long left - why would he throw anything at all, in an empty room?(00:12:35)
Stupidity: Mercusio is looking through FBI files on his computer. The FBI has a horrible database then, since the agents' postings are listed all in random order (otherwise Ben would be working at the White House and not at the school - which is also suspiciously listed without any hint about its location).(01:11:30)
Suggested correction:It is explained that the drug overdose will kill Harlan in 10 minutes based on the dosage. The implication is that Harlan's heart will stop, not that he will become gradually and obviously sick over those 10 minutes. Regardless, based on what they believe will happen, even if they did notice that Harlan wasn't getting sick they wouldn't have the time to test that theory. The fact that neither Marta nor Harlan thought about a potential toxicology report is a pretty major part of the plot, and it is perfectly reasonable given the circumstances. The plot was hatched on the spot within a few minutes and there are several holes in the plan that drive the story throughout the film. Although a brilliant man and a great writer, Harlan simply didn't think of everything.
She explicitly says "You'll feel symptoms in 5" and when he shuts her up putting a hand on her mouth she says "We have 6 minutes."Then his daughter interrupts them and more time is wasted. By the time when he begins his convoluted explanation of the big plan he should have already been disoriented, sweaty and the whole gamut leading to his respiratory failure. And he goes on for minutes after that. It's very true, it moves the plot along, but by what they say themselves (which is from I understand not medically accurate and contradicted also by what happens later in the movie with the second death) they should have realised that time has passed with nothing happening. You could even say it's Rian Johnson's intentional deconstruction of the artificial nature of the whoddunit contrivances! But also, just saying, one of those "Stupid actions and decisions people take in movies, which no-one would ever do in real life."
Even taking that into account, what you are saying is Harlan should have said "Hmm, a few minutes have passed and I haven't felt any symptoms, so I'm not actually poisoned. Carry on then, false alarm." It moves the plot along because Harlan isn't willing to risk Marta getting in trouble for poisoning him and they have less than 10 minutes to act. This would count as a stupidity entry if Harlan didn't care about who took the blame for killing him, but obviously he does. Remember, stupidity entries are not for poor decisions by characters, they are for minor plot holes. This being "an act no-one would ever do in real life" is kind of the entire point of the movie. Nobody believes Harlan would do this because, well nobody cares about their nurse that much. But he does.
The part I was quoting is the description of the category in the metadata on google, or if you prefer the hover text description just above this very page go by "Something just plain stupid. Not as deal-breaking as a plot hole, but something daft, like running upstairs with a killer behind them, instead of out of the front door." I call "slitting your own throat feeling totally fine after you yourself have been calling the minutes with precision earlier", pretty silly, to say the least. Again, this is all stuff the script itself unnecessarily calls attention on. If he didn't mention twice the time before, if she hadn't said that the symptoms happen after 5 but just "your heart is gonna exploded at the 10 minute mark", then, maybe, I would have simply reported the factual error that this is not how it works. It's the script itself that points out (Harlan himself says it twice) the exact minutes, and the symptoms and how they are gradual.
This still ignores the fact that they don't have time to test the theory. They would have to notice the lack of symptoms, and assume somehow that the lack of symptoms after 5 minutes must mean that Harlan isn't actually poisoned, and stop their plan right then and there. The audience knows that Harlan isn't really poisoned, but we don't find that out until later. I doubt very seriously that anyone watching this film for the first time believed, as you suggest, that Harlan obviously wasn't poisoned because he didn't show any symptoms and it was therefore stupid for him to kill himself. It seems to you to be stupid in hindsight, but I honestly don't believe, based on what the characters knew, that Harlan's action was so egregious that it constitutes a mistake in the script.
We definitely had a very different impression watching it the first time. The thought that this old man could be shot a big dose of morphine in vein and calmly think of perfect murder plans for the next minutes was 200% absurd on first view here. I could say that others thought the same but it's just anecdotical and I respect you having a different take. For the rest, it's again just the script itself drawing attention to it. From the mouth of the same character who nonchalantly slits his own throat feeling still fine. It seems egregiously stupid and contradictory.
We don't know that yet. We know that, in their words, he was shot 100 mg instead of 3 (does not matter if true or not, we are fed this information and the characters believe it). Again, the whole scene would have worked if they didn't, themselves, add details. Makes the overdose sound huge, and inserting the 6 minutes mark (which means, barely 1 min till the symptoms show up) before the daughter arrives when more than half of the scene has still to be played, weakens it terribly. Some things are maybe just stupid in hindsight, like the fact that all he needed to do was to write in his own penmanship a suicide note saying he killed himself with an injection once Marta left, but the overdose bit felt absurd on first viewing.
