Stupidity: When the crew think that Dorothy is a robot with a bomb planted in her and is capable of exploding, they begin to think that she is about to explode and attempt to dodge it. Rather than hide somewhere or take cover behind an area that may protect them, they just get down on the floor in front of them and cover their heads with their hands. If they thought the explosion was going to be as deadly as the one they saw on the news, this method of taking cover wouldn't be even remotely effective. (00:24:40)
Stupidity: Natasha is in Norway on the run - Norwegian radio mentions her by name, Yelena talks about her being on magazines, she's very recognisable, and yet she goes into a gas station with her sister without changing her appearance in any way, and loudly talks about being an Avenger and killing people, right in front of the gas station attendant who for all she knows would be on the phone to the authorities the second she's out the door.
Stupidity: At the beginning after Loki steals the tesseract he could easily uses his magic to make a portal in order to disappear from there.
Suggested correction: Loki has never been shown to have the ability to form portals.
Never? He used the Tesseract in Endgame to disappear.
The original entry is saying that Loki could have used his own magic to create a portal. He has never been shown to have that power. If he did, he would have been able to escape the portal Doctor Strange trapped him in in Thor: Ragnarok.
Suggested correction: Loki is a trickster and only has the ability of creating illusions making anyone see what he wants them to see.
Suggested correction: Loki does not possess the ability to create portals with his magic. He could potentially use the Tesseract to do so, but it's possible he believes it needs to be connected to a machine or in some other kind of housing to be safely utilized, since that is how the portal opened that allowed him to come to Earth, and then later allowed him to open the portal above Stark Tower to allow the Chitauri to invade.
Stupidity: All the mutants on the island need Magneto at the last second to take control of the missiles so they don't land and explode. Why didn't Azazel just teleport everyone off the island?
Suggested correction: Given the situation, there was probably very little time to come up with a plan like this. The missiles were flying towards them extremely quickly, and there would have been nowhere near enough time to band every single person together for Azazel to teleport them all out of there in just a few seconds.
There was plenty of time. He could have taken 5 at a time down the Beach 3 miles and came back for the rest. Earlier in the movie he was moving so fast men were falling from the sky at nearly the same time and he was teleporting them one at a time.
Stupidity: The prison where Magneto is held should have had a contingency plan just in case of escape, like machine guns outside the cell, or tranquilizer darts, or gas.
Suggested correction: What good would machine guns and tranquilizer darts be against a man who can literally control and manipulate metal? As for gas, the area outside the cell is so large that any gas would quickly dissipate before it could be effective.
Stupidity: When the Pteradons are loose and flying over the crowds, people run from inside buildings out into the open where the birds are attacking people. (01:22:00)
Suggested correction: A person is smart, people are stupid. A crowd in a panic would do exactly that sort of thing. Like trampling over each other running in panic from a shooting or a fire when not needed. It's the nature of panic in humans as a group to act stupid. It's not a movie mistake. It's actually one of the more realistic parts of the film.
Suggested correction: The dinosaurs were also breaking into/attacking people inside, so they weren't safe no matter what.
True, but one option is certainly safer than the other.
Stupidity: The coast cities should have an alarm that detects the Kaijuns. If they do, they should work when the beasts are few miles away from the shore in order to give the people time to get to the shelters. Instead of that there are still people on the streets in Japan and on the docks in Los Angeles (in the flashback) while the kaijuns arrive from the sea.
Stupidity: Leia was carrying a handheld bomb. Yet she doesn't think to bring it with her later on while freeing Han.
Suggested correction: Novels from the Expanded Universe make it clear that with the exception of guards, nobody is allowed to carry weaponry in Jabba's Palace.
Stupidity: While the train cars are still derailing in front of them, the kids stay on the porch and actually start running toward the oncoming train. Next, they turn around and run in the opposite direction, while staying the same distance away from the train tracks and flying cars/debris. When they run out of the porch to stay parallel to the train, they again turn around and run to the middle of the porch and look like they are jumping around together, clueless where to run to next - running in either direction parallel to the train was not getting them away from derailment. Then they disperse in various directions but stay off the porch. (00:17:24)
Stupidity: This film portrays Michael Jordan and his family living in a relatively modest house in the suburbs. Jordan was one of the most famous people on the entire planet around the time the film takes place. Living in such an area would lead to a never-ending onslaught of overzealous fans, paparazzi, and even detractors.
Stupidity: It's mostly a fun absurdity, but it is somewhat contradictory to showcase the Ghostbusters being featured as the cover story of every major publication and news outlet, and yet to get help not only they put an ad on the newspaper, but a single person applies for the job (which is all it took for them to accept).
Stupidity: When the duke approaches the wall at the end, Snake dives on him and briefly knocks him out. Snake could have easily grabbed his gun back and left the duke unarmed (or even just killed the duke there and then), but just gets up and runs, leaving it with him.
Stupidity: When the marines get the reactor working, Dr Betruger stabs Veronica and kills her so that she will not be able to reveal his secrets to them. However, he stabs her in the lower back, so it would still give her ample time to tell the marines what he is trying to hide whilst she bleeds out. Surely it would have been easier to stab her in the neck or slit her throat.
Stupidity: When Jody traps Michael in his room, he does so by sticking a screwdriver between the the door and the jamb. This likely wouldn't accomplish much regardless, but it especially wouldn't work in this situation because the door opens into the room, so Michael could simply open the door and the screwdriver would fall on the ground.
Stupidity: The X-Men depart for space on a vehicle not designed for space, for an incredibly dangerous mission they know nothing about (and none of them can survive in space at that point), but don't suit up for it in the slightest - and with Nightcrawler and Quicksilver's powers as they are shown later, it'd be easy to do it without wasting time. Not only that, but Xavier communicates with NASA to get the briefing only after the X-Men have already departed.
Stupidity: The creatures in the maze make it inside the living area after the gates open and some of the heroes hide in the corn field. While that alone isn't the smartest thing... one of them keeps a lit torch in their hand burning brightly at night while trying to hide from these creatures.
Stupidity: A-X-L was supposed to be a highly sophisticated and intelligent robotic dog yet it let Sam torch it (without even trying to back away from the flames) and let drones attack it on two separate occasions, each resulting in A-X-L being incapacitated. A-X-L also fell and rolled down a hill, smashing itself. An advanced machine should be able to stay upright! It also seems odd and out-dated that a robot would run on gasoline.
Stupidity: Jimmy and his friends aren't allowed by their parents to go to the opening of Retroland because it is a school night. What kind of amusement has its grand opening on a school night? It would make more sense commercially to open on a Friday or Saturday night.
Stupidity: After making love, Selina notices Batman's scars. She surely was caught in the moment, but, it's something she really was bound to notice sooner. (00:53:10)
Suggested correction: She notices the scars on his back first, which are the worst of those on his body, this may well be the first time she sees his back.
Stupidity: At the very beginning of the movie, law enforcement is depicted executing a no-knock warrant. They approach a house surreptitiously and use a ram to open the door with no warning. When they arrived at the scene, all the cars and trucks in the raid were using flashing lights and wailing sirens. So much for the element of surprise.
