Stupidity: When Roy finally gets to the Lima project in the shuttle but can't dock, he just lets it drift away - he could have at least tethered it to the station to use it for his return trip.
Suggested correction: There is no way to know the reason why he did this. It's plausible, or even likely, that the pod was out of fuel. Not only that, but it could not dock with Lima because it was damaged, so it's likely that the damage played into the decision as well.
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: 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: When Laura goes back to the house to get her bag, she takes off her wedding ring and flushes it. Problem is, she knows how her husband is and doesn't take the time to make sure the ring goes down! But she makes sure there's no other trace of her being there (flushing her hair down the toilet and drying the floor off from her wet feet!).
Stupidity: For a brilliant criminal mastermind, Cyrus makes so many idiotic mistakes. (1) He leaves his entire escape plan hidden in the wall for the guards to find later instead of trying to dispose or destroy them (2) He makes the fatal mistake of trusting Santiago completely and never suspecting a double-cross. At the very least, he should have checked all of Lerner airfield just in case the plane was hiding (which it was). (3) He never notices or even questions Billy Bedlam's sudden absence until he sees his body. Odd considering he notice Santiago's absence immediately. And (4) When escaping on the firetruck, he (pointlessly) chooses to ride on the ladder instead of the front seat where he stands out, and Poe and Larkin both spot him. No surprise his whole plan failed.
Stupidity: When Bishop is first holding the gun on Gina in the cabin, he stands close enough for her to grab the gun and try to get it off him. A man of his experience would never make that mistake, it's one of the basic rules of controlling someone at gun point: Stand more than an arm's length away.
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: There's no reason whatsoever for Mr. Walker to trash the other rooms of David's partners. Someone as tough-minded as Mr. Walker would have been able to recognize the consequences of his behavior. He could have simply trashed David's room and let it be. It simply seems like a plot device to justify David's gang attacking the Walker residence.
Stupidity: The type of steak that Clyde demands has a sharp kind of bone inside that can easily be used as a weapon. No prison would be foolish enough to overlook this fact, especially as the warden had everything double-checked.
Stupidity: Adam, Hannah, and Megan [sitting in SUV with flat tire] saw the Man flashing his headlights, getting out, kicking his own SUV and ranting while holding a machete. Instead of fleeing, they got out of their SUV and saw the Man was wearing a welder's mask. When they returned to their SUV, they didn't lock the doors. The Man ran over, pounded on the front passenger's window and then opened the door. He stabbed Adam 36? times while the two girls just sat there screaming and one said, "Please stop."
Stupidity: Since the main people could not delete, or even change their own Facebook accounts; why not contact Facebook support in order for the company to do it for them?
Stupidity: Towards the end, one of the soldiers (Kieran) gets trapped in the store with a group of child hungries - he was injured in an ambush, but is still lucid/human. He threatens them with a grenade, even though he knows that throughout the story they are mindless and hardly capable of reason. Fair enough as a bad character mistake, but then to allow the hungries to close in on him and not detonate the grenade is inexcusable. Soldiers are trained to fight and, to a degree, accept even death, to obtain an objective or protect the others in their "unit." Dying anyway, he should have blown up the hungries to at least whittle down their numbers.
Suggested correction: A soldier not having the nerve to kill himself is hardly "stupid." Suicide goes against the human desire for self-preservation. Even when faced with assured death it would still be difficult for someone to actually kill themselves and it can't be considered a mistake if someone fails to work up the nerve to do so.
Perhaps so, but soldiers accept that, to a level, their lives are expendable to serve the mission, greater good, etc. Some even seek out a honorable demise. Having many servicemen in my family, this is something repeated frequently. I accept your position as valid! He chose not to use the grenade when faced with his being eaten, and it's tragic. Solely in the context of the movie, it just seemed odd to me then-an opinion.
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 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: Oldboy finds the right Blue Dragon restaurant that the prison uses. But him running after the delivery boy doesn't make sense. How does he know the delivery boy is going to the prison? He knows it's the right takeaway, but that's all he knows. So, would he have a moped, bicycle, or car ready to use surely? The takeaway is a long way from the prison (as he says himself in narration), so he wouldn't just wait around for a moped delivery to run after, especially as a good chance he wouldn't be able to keep up.
Stupidity: The family ask 3 so-called ghost experts into the house. After seeing flying objects in the kids' room, they are suitably impressed. But later on, the female expert is sleeping, one of the men is in the kitchen wanting to cook a steak, and the second man has his back to the monitors, his head buried in a crossword puzzle and he has headphones on with music on, so he can't see, hear or see what is going on.
Suggested correction: The only one acting stupid in this scene is the guy at the monitors. They have to eat and sleep sometime; if anything, having two people awake and one asleep at a time is the cautious route. The one guy goes into the kitchen to cook a steak, but the guy at the monitors, despite being told he'll be the only one watching them, doesn't put down his drawing or take off his headphones, depriving him of sight and sound.
