Stupidity: Throughout the movie, and especially up on the top of the apartment building before they get rescued at the beginning of the movie, Gerry counts 12 seconds to check if someone has been infected. Just to mention this apartment example, he gets blood on his face and spends more than 12 seconds getting up and to the edge of the roof, plenty of time to become "Zeke." He then counts 12 seconds, as if they would actually matter to his infection.
Stupidity: It's very idiotic that Michael and Karen kept the same security password, even after being harassed and not feeling comfortable with Pete being around them any longer. There's no way the pyramid password should have been kept the same, with Pete being able to enter their home, plant drugs, and frame Michael. Changing your security password, the same password that the lunatic cop once knew, would be the first thing to do after his psycho behavior starts.
Stupidity: The secret service officer near the elevator gets shot right in the middle of his head by the Penguin mascot, and she drags his dead body into the elevator. Suddenly he's able to moan and groan and she shoots him again. The guy was very shot in the head, as in graphically. How is he suddenly alive enough to moan?
Suggested correction: A bullet to the head is not guaranteed to kill someone. Movies and video games have taught us that being shot in the head is instant death, but that just isn't the case.
Pretty sure you wouldn't wake up in seconds after a bullet to the head.
Correct. You probably would just lay there stunned while moaning and groaning... exactly like the scene depicts.
He didn't "wake up", he moaned. Which is 100% possible and actually happens quite frequently.
Someone I know shot himself in the head. He was making sounds when found and "lived" for another three months, though there was no higher brain function anymore.
Stupidity: When Drake cuts off power to Hayes' apartment, the cops can't physically make a landlord abide by the laws, and seeing a judge would take months. In the meantime, by keeping the power off in the apartment, Hayes would have had no choice but to abandon his scheme and move on to another victim. With no power in the apartment, it's unusable and unlivable.
Stupidity: Spoiler alert. After the son makes it out, he could get a rescue team to get his dad by going in where he came out.
Stupidity: Instead of breaking into Gordo's house, covering all the furniture in one room with sheets/thin blankets, and waiting for Gordo to return home in order to kill him via a "dramatic re-enactment" (in an adjacent room which was not shown to the audience), Bill could have taken Gordo anywhere to avoid getting caught or calling the police on himself. Had Bill taken Gordo to his already-"wrapped" motel room, he had enough injuries after the fight to claim self-defense against an intruder. (01:43:20)
Stupidity: So he can rescue his wife from slavery, Django comes up with a plan to buy Candie's most expensive fighter and then get him to throw her in for free. Why doesn't Django just offer to buy her directly? Surely there was some amount that Candie would agree to. Even racists like money.
Suggested correction: You missed the point of the plan. They knew if they went in asking to buy Broomhilda directly, Candie would set the price too high. They feigned interested in his best fighter and would get him to throw in Django's wife at a nominal price. They would then just pay the nominal price for Broomhilda and back out of buying the fighter. It's only when Candie is told Django and Broomhilda know each other did he raise the price for her.
Yes, Candie, not Candle. Stupid typo on my part. I disagree with the correction though in the sense of why would Candie raise the price before knowing that Broomhilda was Django's wife? You yourself said in your correction that he only did so when he found this out. They could still have offered to buy her initially.
Because if they didn't feign interest in buying a fighter, Candie wouldn't have even invited them to his place. So the plan was to get him to throw her in for free, rather than risk him setting the price too high (or not even negotiating at all). Candie even figured out what their plan was.
Stupidity: While awaiting their flight home, Nancy told Teri, "Think I miscalculated the tea. I'm not gonna last three-and-a-half hours [on the non-stop flight with no restroom facility]." Nancy then went into the gift shop where Stuart Couch introduced himself, asked if he could get her a drink, and bought her a bottle of beer. Nancy drank at least some of the beer on screen, even though she was already concerned about drinking tea before her flight. (00:59:28 - 01:00:30)
