I'm going with 'Changeling' (not the angelina one) and 'the orphanage'
Descent was surprisingly creepy as well.
Tough one, I watch tons of horror movies, and I just never get scared.. so far, there have been a couple that creeped me out a little, but I was still never "scared" of any.
Ju-On: The Grudge
And to be honest, I really don't know why suddenly Ju-On creeped me out a little bit. When I think about it, there are just so much more gorier movies and way scarier movies that I've seen. I never, ever get nightmares, either. The Ring I watched quite a while ago, just the thought about it creeped me out. The Ring is actually scary though, just doesn't scare me.
I'll admit, it's not something I don't want. Who enjoys nightmares or being scared to hell?
