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 whole premise of the plan is summarized by Helen in the sentence "They don't know Andi is dead, so why would they suspect anything?" However, "they" conspired in unison to financially ruin her sister, and "they" did not answer the mail, none of them. The possibility that "they" all could have gathered and silenced her by force is one of the most likely ones, and yet neither she or Blanc consider even for a moment that the literal crime conspirators could have conspired.
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: (SPOILERS) Despite knowing that Rowena killed the last person who was blackmailing her, Miles tries to use her secret to blackmail her into sleeping with him. Did he really believe that she wouldn't react with such drastic measures like she did before?
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: 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: 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: 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: They go to great pains to lock the nodes behind an explosive lock, then have a debate about whether Riddick's somehow broken in. They eventually unlock them, check they're still in place...then just leave the locker completely unattended and unlocked while they discuss plans, and Riddick of course steals the nodes.
Stupidity: During the auction, we see the dinosaurs are brought into the room and placed in the middle. Thus blocking half of the bidders from the auctioneer's view. (01:16:40)
Stupidity: Red and his gang have a barn full of stuff and talk about other couples and people they have kidnapped, robbed and probably killed. This indicates they have been in the "game" for a long time and been successful to avoid capture this long yet when Kurt Russell didn't want to get in the car, instead of cutting their losses, they went along with kidnapping his wife and initiating the whole ruse of her never getting in Reds truck which is what led to their downfall. Someone with the experience of this that Red has should know not to take such a big risk with a complicated story.
Stupidity: Colonel Sharpe retrieves a gun from a locker on the Freedom shuttle. However, said gun is shown lying flat on the floor of the compartment, with no visible means of securing it, which would hardly be standard NASA procedure given the shuttle undergoes a high-G launch, orbital manoeuvres and various other high acceleration events. A loaded gun bouncing around is the last thing anyone would allow on a shuttle. (01:42:39)
Stupidity: Mike Roark is supposed to be the director of an agency that is in charge of coordinating all the resources of the city in the event of a natural disaster, but he doesn't know what a "geological event" is, not to mention magma?
Stupidity: When Michael goes to Judith's room, all she says is, "Michael, what are you doing in here?" She doesn't even ask why he's all bloody.
Suggested correction: It's Halloween, and she most likely thinks he's got into the spirit. Let's also not forget how she treated him earlier when she blew off taking him trick or treating. It's obvious she doesn't care about him at all and is beyond self centered so it's not surprising she wouldn't comment on it.
