Stupidity: It was pure stupidity for Riggs to bring Rika back at her residence after escaping the hit on Riggs. The villains know where Riggs' love interest lives and this nor the option to hide somewhere else or safer never occurs to him?
Stupidity: There is no way a fighter with a brain would risk serious injury to themselves before a fight by continually punching a frozen rack of meat in a freezer slaughterhouse. There is nothing to gain by doing this, and it would only result in both fists being broken.
Suggested correction: In fact, Sylvester Stallone permanently damaged his knuckles filming the two scenes. He obviously did not realise how dangerous punching a side of beef would be, and it isn't out of the question that the character Rocky Balboa wouldn't realise this either.
It shouldn't take a rocket scientist to know that if you punch or hit anything with a bare fist against anything solid, rock hard, you will damage yourself badly.
Absolutely, it shouldn't, but that is not what the "Stupidity" category is for. It is unintelligent for someone to do this, but that is not a movie mistake. Sylvester Stallone really did punch that beef and really did injure himself, so it is not something that is out of the question for a character in a movie to do.
No, but it is out of the question for a man with painfully damaged knuckles to go fifteen rounds with a world heavyweight champion boxer. In fact, Rocky would probably have failed the compulsory pre-fight physical and would have been ruled unfit to fight.
Where in the movie is Rocky experiencing "painfully damaged knuckles"? With your logic, the fight would have most likely been called long before the 15th round, due to the very unrealistic and improbable punishment the 2 boxers were inflicting on each other.
Stupidity: The characters wish for the resurrection of just one person (Roshi) rather than everyone killed by Piccolo as would be natural (and as they do in anime and manga). Okay, Piccolo in this movie sucks at killing and resurrecting Muten covers 50% of the total body count, but they can't know that.
Stupidity: Robocop is just about to be unveiled to the press for the first time, and they decide right beforehand is the perfect time to upload a massive amount of data, including his own attempted murder. Then, they seem shocked when that causes problems. No reason to do that right before a very public, time-sensitive moment except for the sake of the plot.
Stupidity: In the opening scene with the military convoy, the two soldiers in the lead vehicle never notice the car veer into their lane, even though their faces are bathed in bright light from the car's headlights. They simply ignore it and keep talking to one another.
Stupidity: When Wolverine is trying to prevent Deadpool from sacrificing himself by destroying the time ripper device, he repeatedly pounds his fists against the glass panel on the door to break it, to no avail, which leads him to then go to another heavy door, which he is only able to break down in the nick of time. Wolverine's adamantium claws would have easily destroyed the glass on the other door, without him having to repeatedly and futilely punch it.
Stupidity: The 1st time Foley enters the warehouse with the woman, 2 guys enter with the wooden box and black bags on top to transfer the bonds, then take it back to the truck. Why enter the warehouse at all when they could've put the bonds in the bag anyway, inside the van? They had no reason to go to the warehouse at all. (00:42:20 - 00:43:25)
Stupidity: While Tommy and Snake Eyes are trying to escape the docks in the truck, the Yakuza men surround the truck and stab over a dozen swords in all parts of the cab. Not one of the men ever thinks to use their sword to slash the tires, allowing the heroes to make an easy escape.
Stupidity: As Powell was standing at the completely wrong "eye" in the temple to begin with, all Lara had to do was say nothing of his mistake, he'd never had got the first piece of the triangle to begin with, world safe for another 5000 years.
Stupidity: When Susan is on the balcony with the man trying to kill her, she pulls out her gun with one hand (she's leaning on the other hand). He says she won't shoot because the gun's magazine has fallen out and Susan gives up and drops the gun. However, if there is a round in the chamber, the gun can still fire without a magazine in it. As trained as Susan is suppose to be, she should know this. But, if there's not a round in the chamber, then, as a trained agent, Susan is ineptly prepared to use her gun. If there's not a round in the chamber, pulling the trigger will not fire the gun nor will pulling the trigger chamber a round. But she would need both hands to chamber a round and she only has one hand free. There is the occasional gun that has a magazine disconnect safety, but it would be stupid for field agents to have one since they may be in a situation where they need to fire without a magazine in (such as this situation).
Stupidity: In 300 years, in an empoverished world full of people hungry for techs, nobody ever tried to remove the ship from a small pond barely 15 feet deep, and everything inside seems intact. It is mentioned that few tried because the technology is hard to sell being unknown (which is laughable), but surely some would try to strip the ship for alloys, and certainly the lights and monitors wouldn't stay untouched in a world based on scavenging. For 300 years and so close to the city, even.
Stupidity: The train which takes M from New York to London arrives looking like an old tube train, then when she's on board converts into a high-tech train, to her amazement, and whisks her across the Atlantic. Except...why did it ever look like a regular train? She's in a MIB station, it's only used by agents and aliens, it goes to another MIB station, and when it arrives and people get off / on before it continues its journey, it stays in its high-tech form anyway.
Stupidity: When the saw yo-yo comes down for the third time, Bond grabs the cord to pull the wielder down off the gallery. That was, when you think about it, a patently bad idea. If the yo-yo hadn't become stuck in the desk, Bond would be collecting his fingers in his hat (note that the blades are still spinning as Bond grabs). (01:15:45)
Stupidity: When Rumsfeld is on his roof as a look out, he has a clear view of the neighborhood, even at night. However when the Klopeks first come home that night (and realise that someone is in their house), Rumsfeld fails to notice their car until they return again with the police. (01:20:00)
Stupidity: In the scene when the cook is torched, why didn't he just jump out of the longboat into the water? Why get burned?
Suggested correction: It would be pointless. If he ran away, Blackbeard would just come after him and make him suffer greatly. At least the fire is quicker than torture or being zombified.
Hogwash. Fire is even more painful than torture.
Not only that but, it's only speculation what would Blackbeard would do to the man if he had survived.
Stupidity: At the very beginning of Donnie Yen's fight inside the CIA conference room, security barriers start descending in the room, windows first and then doors, but somehow the exitway for him (which even communicates with the main elevator. Not a secure bunker or anything) starts shutting down a minute later so he can baseball slide past it before it closes. That's pretty nonsensical security protocol. In fact, the whole operation is successful because apparently the CIA Headquarters lack any cameras and sensors in the corridors, security at the lower floors, main doors, perimeter, especially during the top brass meetings (that happen in a room with huge windows with reinforced glass a man can break jumping at it). (00:09:20)
Stupidity: There is no reason why any person as intelligent as Janet would keep the knowledge of Kang secret from her family. The extended Pym family are the only people in possession of the one thing Kang needs to escape. The brief explanation she gives is that she wanted to protect her family, but this makes absolutely no sense whatsoever, and she makes no attempt to explain how this secret keeps anyone safe.
Suggested correction: She is obviously scared out of her mind concerning Kang. She, through her fear, had hoped that him being trapped in the Quantum Realm would stay permanent as long as nobody knew about it in the normal universe. In that way, she tried to protect not only her family but the entire universe.
Not only does she not say that she is "scared out of her mind", she also doesn't act like it either. There is no indication that she is so frightened by Kang that she has lost her senses - quite the opposite, actually. She appears to function rationally and intelligently in every other area concerning Kang, except of course for simply telling anyone how dangerous the Quantum Realm is because the movie wouldn't have a plot otherwise. It's pretty egregious and wildly ridiculous.
Of course, she doesn't say that or act like that. But what she saw of him, when she touched his ship, scared her enough to go to all that trouble to keep him in the quantum realm at all costs. She thought it would be safe to leave, that he was trapped forever. Her judgment was wrong, probably caused by her fear. She is only human.
"Fear" is not enough to get past this level of stupidity. My point is that she doesn't act so frightened; she isn't irrational in any other way. It's just a flat-out, stupidly written element of the film that is impossible to believe. There is no way on God's green earth she should keep this secret, even after her family has made it to the quantum realm. I get that the movie is trying to say she is frightened, but this goes well beyond making any kind of sense at all; it's ridiculous.
Part of the stupidity also involves Janet's action in the mid-credit scenes of "Ant-Man and the Wasp," where she actively helped send Scott into the Quantum Realm to get quantum energy. If she was so afraid of a signal being sent to the QR, she wouldn't have let Scott go without explaining the dangers of going. This film seems to ignore that and instead seems to focus on Janet simply not wanting to discuss her involvement with Kang and her guilt, thinking no one would go back to the QR.
