That's actually the problem I have when looking up horror movies, a lot of the highly rated movies on the internet are about psychopaths and murderers and diseases and stuff. Those don't scare me or my sister at all because we're huge bad-asses and we're not afraid of anything real. Like we were watching The Collector the other day and all we were doing was yelling at the characters on screen about how stupid they are, that movie was awful by the way.
We like spooky stuff, ghosts and apparitions, psychological manifestations, things that aren't real but are impossible to fight if they were real.
