Do we really like watching blood and guts everywhere, spiders that grow as big as horses and eat you up? I don't know, maybe human nature is that twisted and we actually enjoy watching horror movies. I personally hate them. I don't see anything exiciting in watching people being tortured and being in tension for hours. So I can't really understand why we should pay for two hours of fear, disgust and terror, if they are consider negative feelings?
We all get very upset when someone scares us by hiding behind a door but we just like to go to the movies knowing we're going to freak out. Isn't it ironic?
Maybe a person is not actually afraid while watching the film or maybe the euphoric sense of relief at the end of it makes everythign worth it. I don't really know. Maybe it's just that people like to experience terror and relief at the same time.
