A Horror Movie I Kinda Want To See

I don't like horror movies. There, I said it. I find no joy in being startled or scared, I get that enough from my doorbell. Every once in a while, however, a horror movie comes around that I actually want to see. Well, usually it's sci fi or a supernatural thriller, and not just a hack n slash gore fest. This time it's Devil. I don't know why, but this preview really interests me. I think it's a pretty interesting and scary premise. Strangers trapped in an elevator with crazy things happening when the lights go out. It looks fun.
This movie is not directed by M. Night Shyamalan, only written by him. I think putting his name in the trailer will be less of a benefit than it used to be. The thing is, he is pretty good a writing thrillers. I really enjoyed The Sixth Sense and Signs. I think he got a bit caught up on the twist ending thing, but if you ignore that, the guy knows how to make a good movie. I hope this movie doesn't try to have a huge twist, but I think they'll try to stump us with the mystery of who the Devil (or whatever). For the record I'm guessing it's the brunette woman. She says something ominous in the beginning and is the first to be attacked (red herring?)... but who knows.
Anyway, it looks interesting. You may not think so, but I do. One of the only other horror movies I really liked was The Descent, another very claustrophobic thriller. Other than that I can't think of many horror movies that I really enjoyed.
