Yeah most of them. I mean come on... You have a cell phone in your hand... You saw your friend (you know, the one who actually had a weapon) get yanked away/killed/hacked up by a monster.... You don't call for help You decide to go get him/her back yourself?? LOLOL
Now, ghost stories and psych thrillers... the ones that mess with the mind, those can be scary. Halle Berry in Gothika was kinda scary until the end. That's where it became "unscary" for me.
i find most horrors to be quite funny myself as well...cause the stupid guy is usually one of the best deaths and everyone does stupid things to get themselves into worse trouble
I can think of the most blatent example...friends have been dying, everyone is in a room together to keep safe, but the ONE guy has to wander off by himself...gee I wonder what is going to happen to him?
In reality, that may be how people would act(in some movie, not all).
Ex. Vampire sneak up on a person. You think moron there a vampire behind you! But the person doe not know that. And that the whole point.
