There are quite a good few movies where they don’t act brainrot levels of stupid, though. In fact, the only movie series I can think of (not in the headspace to pull up a ton) where they’re explicitly stupid is the Final Destination movie series… and Tucker & Dale vs Evil, but they’re supposed to be stupid in that one (and it’s great).

I don’t mean curious where they should be scared, but, “duhh I’m running towards the monster/danger” dumb. That stuff jumps the shark so easily.

Maybe some of the newer shitty horror movies like the poobear one, popeye, peter pan, and bambi ones? Though TBH, they were on in the background and I barely even remember their plots, let alone how dumb the characters were…

Sometimes the “normal” levels of dumb are fully explained by the writers not having the time/screen time to pull off a “smart” reveal, too. They just need something to happen, so it does. Fully forgivable if the rest of the movie is good, IMO. Unless it’s like… the established smart and level-headed character suddenly fucking up big time where they shouldn’t even be panicking or something. Then it’s always annoying. lol
