Stupidity: Peter Parker watches Richard Parker's last message, the upload he did on the plane to his super encrypted server. As he does that, the interface used is one of a mail and there's even the sender; "Rich-Park@oscorp.web." So Richard Parker sent his dying message he wanted to keep from the evil corporation...through his evil corporate mail account, and to an account that contains the location of his secret lab, "Roosevelt." (01:32:50)
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: The creatures in the maze make it inside the living area after the gates open and some of the heroes hide in the corn field. While that alone isn't the smartest thing... one of them keeps a lit torch in their hand burning brightly at night while trying to hide from these creatures.
Stupidity: In the exciting denouement when the SS company approach the ostensibly disabled Sherman, the SS would have just walked around it. A burning tank was a common occurrence. I doubt they would start climbing on it and they certainly wouldn't start charging at it individually as to get mowed down. The SS were well trained units. Such stupidity is unlikely.
Stupidity: Liv was a graduate psychology student when she met Bill and, after marriage and being physically abused, knew that the leaving Bill put her in a (potentially) very dangerous situation. It is best if the abuser does not know where the victim is "hiding" after separation, but Liv brought along Carol to pick up the kids - and they were going to be staying at Carol's house.
Suggested correction: She brought Carol along as a chaperone/protection when she picked up her kids. She didn't announce to Bill that that would be where she was going to be staying, she only told her kids that when they had already driven away from the house. Bill didn't seem to know who Carol was anyway. Even if he did manage to find out where she went, she could have easily got a restraining order against him.
It is more likely that she brought Carol along for emotional support and to act as a witness. If she were looking for protection, she would have used a police escort. It was implied they were going to be staying at Carol's, but, even if not, Carol's presence offered Bill a hint of where to start looking for Liv, and there should not be any leads. Liv unwittingly put Carol in a potentially dangerous situation - if Bill went to Carol's looking for Liv, and Carol truly did not know where she went, Bill would insist that she did and threaten or do worse if Carol didn't tell him. Remember how Bill drilled all the kids about where Liv went, checked their phones, accused Sam of knowing more, then got them into the car and drove like a maniac? Bill has a temper and propensity toward violence (at least when drinking, which he did everyday). Court orders take time to get, but are not very effective. Numerous women who had restraining orders against abusers ended up six feet under.
Stupidity: Do the military routinely show up at a civilian's house and then pump thousands of rounds into the house without even verifying if anyone is inside? I've heard of suspension of disbelief, but this scene requires driving it to a vacant lot and abandoning it. (01:11:30)
Stupidity: When he's using carbon monoxide to poison the corrupt detective Frank Masters, the windows in the car were operated by the key fob. Unusual, but OK. Maybe. But the detective could've simply opened the doors after McCaul left him in there. The door worked when he was forced into the car. (01:24:30)
Stupidity: Four H.S. seniors are sitting in an SUV. A storm quickly intensifies and Billy gets out of the back seat to get a better look (wipers are on "fast"). Seconds later, Billy spots a tornado coming. Marcia (driver) tells Billy to "get in." Needing to flee the fast-approaching tornado, Marcia wants to leave as soon as Billy is in the SUV, so she yells, "Billy, get in!" The tornado is feet away when Billy closes the door - whew, he's safe! Marcia STARTS the SUV when the tornado starts bashing it. (00:01:14 - 00:01:38)
Stupidity: If Leo wants to kill his son's killer at any cost and no matter what happens, he should've gone directly to his House when the purge starts.
Suggested correction: He absolutely is headed there, but we see at least one incident where his path is blocked due to people out purging, and he needs to turn around. That detour caused him to go a different route, which led him to the mother and daughter. We even see him struggling with the decision on whether or not to help them. He decides to do so, and the rest of the movie unfolds as we see, but there is no mistake.
Stupidity: When Amy tries to use the security cameras at Desi's house to make it look like he raped her, wouldn't the cops be curious as to why there was just one little scene - and not 30 days worth of footage? Wouldn't they question what happened to the rest of the footage (showing her being looked after by Desi and living comfortably), and why that little bit showing her crawling on the ground was left undeleted. Also she tied lace around her hands. Anyone could break material like that if they tried hard enough. Why would Desi risk that?
