Cerebral ghost stories, like 'Insidious'.
I love that movie!
I love ghost stories, or anything with a supernatural elements, such as demons or other spirits. Those are by far my favorite. Slasher movies just don't interest me.
I like something that has an intelligent, original & creative story line like the film 1408 with John Cusack ba<x>sed on the Stephen King novel. Slasher movies like 'Hostel' have next to no story line and are all blood and gore which I think is unhealthy for viewers especially younger viewers who shouldn't watch 18 rated but lets face it often do. I would be wary of someone who collected slasher movies!
Ghost stories! Like the grudge and the amityville horror.
