Stupidity: If the song "Beyond the Sea" can be continuously broadcast on the radio station as a "cryptic clue" that there are survivors living on the island and the aliens are unable to swim, then someone could verbally announce that information over the radio and otherwise communicate with other humans. The same thing about how Regan's hearing aid incapacitates the creatures. Rather than explaining how to weaponized the high-frequency sound, only the hearing aid's noise is broadcast and anyone hearing it has to figure it out.
Stupidity: Bori Khan is a skilled archer and a man without honor. He's not fighting fair, and cares just to win, as established and explicitly said. He shoots an arrow at Mulan, the Witch gets in the arrow's way sacrificing herself to protect her...and for no reason whatsoever he does not shoot anymore, giving the chance for the two girls to share their very special dramatic moment together, but creating a colossal plot contrivance. It is a know movie cliche for the fight to 'pause' around the main character, but here we have a sniper who desists completely (he won't shoot anymore) for absolutely no reason. (01:29:00)
Stupidity: Diana and Steve are both characterized as heroes and highly moral individuals, but they both are perfectly fine, without giving any shadow of a second thought, with the fact that Steve is inhabiting the body of a real person, with a real job and friends, completely innocent and whose life has been taken. We don't ask for a movie to cover every possible nuance, but they make reference to his job, use his stuff, endanger the innocent body and use it 'for pleasure' too. They make a big deal of Cheetah losing her humanity, but what the heroes do is arguably worse.
Suggested correction: While this is bad writing that makes them unsympathetic, it is not objectively a mistake. They endanger the man through Steve because the entire world is at stake. They have sex using his body because they, like the writers most likely, do not consider it rape because there's no indication that the man is conscious in Steve's body or that he'll ever find out (So closer to date-rape), and ultimately, Diana wanting Steve to stay in the man's body forever, while arguably out of character, is a character flaw they both realise she needs to overcome by the end of the movie.
Not objectively a mistake? Actually I agree! Stupidity entries are in a tab separate from the proper "mistakes" tab for a reason; all those behaviors that are not full plot holes but happen against logic and character, just because they are being a tool for the plot. The movie does not make them unsympathetic by design; that would be good writing, that wouldn't be stupid, it would be human. But no, their love antics are never characterized as problematic or inherently creepy. The choices they make and that are outlined in your comment are glossed over; the movie hides the face of the guy but they both see it when they 'rape' him and when they risk his wellbeing, When she gives up on him she does it to get her powers back, she is not overcoming a character flaw, since the presence of the "other guy" is not addressed even at that moment, even if they see him. (if Steve were in a new body, the scene would have played exactly the same). Nobody could act this blasè.
Everything you've said in the stupidity entry and comment is your opinion (well, probably the opinion of the one YouTube video we've all seen where the guy bashes the film and then others repeat his opinion). Wonder Woman sees Steve, not the man whose body Steve is in. Not to mention we don't hear all their conversations about the situation because it would become clunky dialog. And before she starts losing her powers, the two really had no idea what had happened to the man. But nothing in the film regarding this situation is out of character of the "good guys" because we've never seen them in this situation (nor has anyone actually been in this situation to claim "nobody would act this blasé).
I invite you to rewatch the actual movie and not any youtube video; she sees the guy, they both do; he's never Chris Pine, who is 'canonically' never in the movie as himself. Chris Pine is what we, the audience, see. Look back at the scene of the mirror. They explain it. She says "He's great, but all I see is you." Not meaning that she LITERALLY sees Steve, but that she knows it's Steve and so she thinks of him. He even says, about himself, when he tells her to look for other men, "What about this guy" and she says "I don't want this guy." What's in the movie is out of character for any human being who is not delusional to the point of actually seeing the face of someone else. Which is what the movie needs to turn us viewers into to make the plot work.
Nothing in the film suggested to me she sees the other man after Steve comes back. I was basing my comments on watching the film (the YouTube comment was because this mistake is the same rehashed comment found there). When the camera pans around and the audience sees Steve, I took it to mean Diana sees Steve. When she says "all I see is you", I took that to mean she literally sees Steve. The mirror scene was to show the world still sees the man, but not Diana. But I can understand if others' take away was Diana sees the other man but just knows inside her heart it's Steve.
She sees that guy at the party, and only through Steve's words she then realises it's him, which the movie portrays from then on by showing Steve to us. The earlier part of the mirror scene is even more clear. He says; "Look at you. It's like not one day has passed." And she replies jokingly "I can't say the same thing about you." He does not look the same! And he in fact then goes to the mirror saying, "Right, right, right." and comments on the look of "He." So yes, I do firmly believe that it's what the movie says. If I may; the fact that some people on Youtube posted a video saying some things does not mean that anyone else supporting a specific idea - which does have a foundation in what the movie said, as I hope I clarified - did not reach the same conclusion and should be dismissed because they are lazily rehashing hersay. Glad you at least see where I come from, even if you may have not read the movie facts the same way I did.
Stupidity: The guy who offered to help Rachel go to her car at the gas station and get away from road-raging Tom walked directly in front of the path Tom would be taking to leave. When the guy realised Tom was going to run him over, he went onto the road instead of toward the store where he would be safer. Also, the guy - knowing Rachel's situation - foolishly told Tom that he got his plate number, which served to aggravate Tom into driving into him. (00:32:15)
Stupidity: At the outdoor market, Libby told her old girlfriends that she'd "be right back" and went into a stall in the women's room. Soon, her girlfriends came in but stayed in front by the mirror. Without bothering to look if anyone (particularly, Libby) was in one of the three stalls, they started talking negatively about Libby (e.g, " Ugh, what is it about her that is so irritating?", "I feel sorry for her", "She looks like she's wearing a Halloween costume", "She's like a lumberjack"). (00:55:08 - 00:56:00)
Stupidity: A zombie is climbing up the apartment wall and is almost at Aidan's balcony railing. Instead of trying to push the Zombie off while he had the advantage (and there was a surfboard on the balcony that could have been used), Aidan ran inside and locked the door to the balcony. This furthered the plot and added excitement by having zombies coming at Aidan from multiple directions. (00:43:09)
Stupidity: When Liz sees the dead deer blocking her lane, instead of merely going around it (using the opposing lane on a rural road without jeopardizing her safety), she exits her vehicle - leaving her three-year-old daughter unattended in the back seat - to "look" at the deer. This furthers the plot by giving the "werewolf" opportunity to attack and kill her... as well as her daughter Miley. (00:42:35)
Stupidity: This lady lives in the United States, she obviously doesn't have a criminal record, she can go buy a handgun or rifle, heck she can buy a handgun and rifle and extra magazines and ammo to defend herself, but she chooses golf clubs and baseball bats and mace. (00:00:01 - 01:20:00)
Stupidity: The whole movie happens for unbelievably convoluted causes. Despite their friendship and the simple fact that he still runs an occult shop (showing that he's not exactly insensitive to the past), Ray in years never spent a single moment to check on Egon's whereabouts, which he knew, or listen to him. The city has Shandor's name all over and any cursory investigation would have unveiled the connection. Assuming of course that Egon turned into such a lunatic he couldn't do the namedropping himself.
Stupidity: When they're tied up in the lab it's not that hard to escape. They have this loose straps with clips. (01:35:40)
Stupidity: Becky possessed the mysterious key that the four neo-Nazi prison escapees were at the lake house to retrieve. Becky didn't know what the key was for, so did not have a vested interest in it. By first denying that she knew where the key was and later refusing to give it to Dominick, her father was killed. Had Becky simply handed over the key when Dominick asked for it, it is possible no-one would have been hurt/ killed. Becky keeping the key with no importance to her served to further the plot.
Stupidity: Matt told Joey they could not check on the guard in the hole because they had committed the "perfect crime" but could get caught if the guard got out. Matt later told his friend Tom "everything" about stealing from Ms. Dillard. Bragging about what they did is certainly no way to help ensure they would not get caught.
Stupidity: Molly was being hunted and didn't know if she could trust Rayburn when he encountered her. Rayburn told Molly that he wanted to help, wouldn't hurt her, put a blanket around her, and even carried her in the woods for some distance. When he put her on the ground (along with his backpack and rifle) to go find the rope to open the pitfall doors and had his back turned, Molly got out from under the blanket and hid nearby. Rayburn quickly found Molly, and Molly made a lame attempt at attacking him with some kind of club. The next day when Rayburn and Molly were in Rayburn's house and her hunter showed up and attacked Rayburn, Molly grabbed Rayburn's rifle and fired several shots at the hunter. Molly obviously knew how to use a rifle, so it was asinine for her to have hidden from Rayburn the previously night without taking his rifle (or the blanket). (00:36:22)
Stupidity: So if Harley Quinn drove the truck to blow up the plant, wouldn't she have had to drive through all the cop cars at the bar murder scene? We know it was the same street because the cop gives the necklace to the detective. (00:10:58)
Stupidity: After Ethan "lands in the future", his spacesuit catches fire. He removes his glass head cover (so he can enjoy the smoke in his face?). Instead of following the well-known "drop and roll" technique for smothering/ putting out the flames, Ethan stood there and patted the flames on his wrists and legs with his gloved hands, but the flames were spreading. His next idea was to remove the spacesuit. After a short struggle getting it off, Ethan was no longer "on fire" - so now he dropped and rolled. (00:29:39)
Stupidity: Crystal knows she is being hunted and in a very dangerous life-threatening situation yet, after she kills "Ma and Pops" in their Main Street Market, she grabs only a few shotgun shells out of the open box instead of taking all of them or as many as she could find. Also, she walks some distance to the store but did not take anything to drink or eat. (00:27:00 - 00:27:55)
