So what's up with the whole tying people up with chains, torturing them and holding them hostage $hit? That whole concept is not even scary IMO. It's gory, but it ain't all that scary.
I don't know man, but I like scary shit that's based on supernatural stuff. Demons, religion and shit like that. Images of upside down crosses, pentagrams, people speaking in aramiac/latin, possession... trip me out more than anything. It's just more realistic and at the end of the movie makes you feel wierd because you know some of that shit can really happen in real life.
