When I was younger, Witchboard scared the crap out of me for some reason. I saw it again a few years ago and wondered what the big deal was. I mean, Tawney Kitaen in bad '80s clothes is scary, but not in that way.
I think I'd have to say that the scariest movie for me at this time in my life is the remake of The Hills Have Eyes. It touches on a lot of things that bother me, like long-term captivity and being stranded far from home. I think the worst part is that everything happens to one family, and they always see each other being killed and abused. This creeps me out way more than the random group of drunk teenagers partying where they don't belong.
