Stupidity: After Noah shoots the Humanity Bureau vehicle following them, they continue down the road and stop at an old abandoned building that still has some sort of running water in it. Lucas has to go to the bathroom so his mother just lets him wander off by himself to find a restroom. She doesn't go with him or make sure he's fine. And this is in an area where they know that most of the residents are hostile, and they are being chased by the Humanity Bureau. Noah even calls her out on the stupidity of her letting Lucas go by himself and she claims it's because he needed to do number 2 and that Lucas insisted and he's not a little kid any more... Which doesn't excuse the stupidity of the action of letting an 11 year old go by himself to find a bathroom in such a situation. And ultimately it does lead to him getting found by Agent Westinghouse. (01:08:30)
Stupidity: Harrigan leaves his partner's badge on his grave where anyone could take it and use it to impersonate a cop or abuse it in other ways. (00:50:15)
Stupidity: I won't begrudge Father Lamont for instinctively grabbing for the first thing in reach to try to smother the box on fire (even if it is a pair of wooden crutches), but you'd think at some point he'd notice that he's just spreading the fire and making it much, much worse, but he keeps at it until the doctor finally returns with the extinguisher.
Stupidity: In the Anubis universe, immediately around the time Lawless says, "Something's wrong," if you look closely, by Lawless, you see the two police officers behind Jet Li walk away to leave Lawless completely unprotected from behind. I understand it's a parallel universe, but that's some really bad police work to leave a prisoner wide open like they do.
Stupidity: The whole movie happens for unbelievably convoluted causes. Despite their friendship and the simple fact that he still runs an occult shop (showing that he's not exactly insensitive to the past), Ray in years never spent a single moment to check on Egon's whereabouts, which he knew, or listen to him. The city has Shandor's name all over and any cursory investigation would have unveiled the connection. Assuming of course that Egon turned into such a lunatic he couldn't do the namedropping himself.
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)
