cause they think theyre funny
Because being scared is fun for them, rather than terrible.
Because its much fun you get scared
They are fun, to me, not scary
They're often so bad and so transparently manipulative of current culture and human fear that it's hilarious. I watch them for the lols. Also, most A listers that are actually good refuse to act in horror films. The writing is usually terrible and they often get a bad rep for it. So the crappy acting and production quality in a lot of horror flicks are just super funny to me.
Horror movies may be the single best thing in the world next to yoga pants of course.
Horror movies are fun! Apparently people who don't like them really can't understand.
Thrilling, gets adrenaline pumping
It's not torture
