Stupidity: Very soon after Damon is stranded, one of the many satellites around Mars inevitably picks up the fact that he has moved various objects around his site, indicating that he's still alive. Yet it never occurs to him that this would obviously, eventually happen. In which case, his best option would be to simply spell out a message with debris and stay put instead of planning some 50-day journey.
Stupidity: When the Woolworth Building collapses and the gang runs into the convenience store to take cover from the dust, Marlena was last seen behind Hud and with Lily, Rob, and Jason. Switch to everyone running from the dust cloud, Marlena didn't make it into the store. Upon exiting the store, the gang finds Marlena stumbling from nearer to the Woolworth Building meaning she would have had to run toward the dust cloud, through the screaming crowd which was running away from the building.
Stupidity: Cobb convinces Fischer to enter a dream saying it's Browning's dream. A couple of scenes later he says it's Eames' dream, in front of Fischer, who doesn't know Eames was impersonating Browning. (00:51:35)
Suggested correction: Firstly, the Browning that the team "catches" is not Eames, it is a projection of Fischer's subconscious. Eames was only impersonating Browning in the first level. Secondly, Cobb doesn't say they are going into Browning's dream, he says they should put him under and do to him what the kidnappers were planning to do to Fischer. That is, use Fischer as the subject of the next dream level. Fischer knows that Eames is the dreamer on the third level, he even jokingly asks why Eames couldn't dream of a beach. But he thinks that Eames is part of Mr. Charles' security team. He believes that Browning is to be the subject on the last level when in fact, Fischer is the subject on each level. Because of how effective the Mr. Charles gambit was, Fischer is unaware that the team has been fighting his subconscious all along.
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: Wouldn't it be common sense to have more than one remote to control Robo-Cain? That way, if he destroyed one (and he did), they could still use one to shut him down from a distance (as long as they can dodge the gunfire).
Stupidity: All of Robbie's circuits have been burned out as a result of Morbius ordering him to kill the Id monster. The crew only has 24 hours to get the ship loaded and a safe distance away from Altair IV before it explodes. But one or more of the crew spends the little time they have fixing Robbie, a very sophisticated piece of technology, who is working the controls at the end of the movie.
Stupidity: Mar-Vell's laboratory is a spaceship that the captions identify as an imperial cruiser, not exactly the kind of thing that can go missing unnoticed. Since the Kree were so determined in finding Mar-Vell's work and are so attached to it that they keep Carol around, how is it possible that in 1989 or ever since they haven't looked for her cruiser? Carol manages to uncloak it without using any secret code (that she wouldn't know since Mar-Vell told her about the whole alien thing just barely before dying and was not privy to any security measure).
Suggested correction: Decloaking the ship still necessitated knowing its location. The Kree didn't know where it was, so couldn't decloak it.
But they don't even look for it. He literally goes "oh, well, the engine is gone, let's go home", without any attempt to look for Mar-Vell's project or, again, the big cruiser thingy. Something so important, and yet the empire does not care about it to probe around for it.
In your other entry you suggest Ronan doesn't even know about Mar-Vell's project. More likely he doesn't care, since he is a fanatic who worships the old ways. Its logical he will ignore it, especially when his interests have been turned towards Carol flying around blasting through his ships. Which he later forgets for whatever reason as well.
No, no, I am referring to Yon-Rogg in the past, and the empire as a whole: they are after whatever work Mar-Vell was doing, to the point of keeping around with a very flawed brainwashing plan an incredibly dangerous being created with that technology, but don't look for her ship or evidence of her work, at all. 6 years with the knowledge that somewhere around (or on) Earth there's the key to unlimited destroying power and/or a hyperfast engine, and everyone is like "Meh, whatever" for no reason.
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 Michael is heading to the hospital and he just learns that the Cloverfield Station is gone, the whole scene of him driving is super unreal. It looks like he's not even driving, like it's a self-driving car or something because the steering wheel doesn't move at all while he's driving, and he isn't looking at the road (staring into space). The whole scene just doesn't feel realistic. (00:43:48 - 00:44:30)
Stupidity: The Analyst wishes to hide the true identity of Neo from anyone inside the Matrix, so his appearance is altered. But in this new Matrix Neo is also named Thomas Anderson, his name from before he was pulled from the Matrix originally, and he is a famous game developer that created a video game series called "The Matrix." It is frankly astounding that anyone actively looking for Thomas Anderson would not immediately see through this ruse and instead would be fooled by balding hair.
Stupidity: Since we get frequent POV shots from their eyes, we see exactly what the creatures hunting Venom see. Even when the Codex disappears from their view, they can see distinctly Venom's shape, and they have no problem using their appendages and brute force against any and every creature. There are moments in the movie (such as the scene in Vegas) when the Xenophage just stops for no reason; even if the big blinking thing is gone, you can still see the shape it was attached to.
Stupidity: Central to the plot is the layout of the Mars lander. There are no seats or any restraints of any kind in the lander, which is ridiculous. Spacecraft require safety belts in order to prevent astronauts from being injured during rapid course corrections. Additionally, ordinary rolling desk chairs would not be sent into space, and would certainly not be placed on a landing vehicle.
Stupidity: Stitch wakes up in a kennel with dogs at the animal shelter. When Lilo picks him out and they walk out of the kennel, the lady freaks out and tells Nani, "We thought it was dead, it was hit by a truck!" So, what was thought to be a dead dog was put into a kennel with other living dogs. Think about that for a second. (00:24:54)
