I liked The Descent a lot.
A group of friends go caving in the Appalachian mountains and they encounter some very strange things.
Like the alien in the X-Files: Fight the Future movie, there’s something about a pasty humanoid creature that screeches instead of roars that really un-nerves me.
The movie has more of the suprise scares instead of the suspense scares (that Mr. Hitchcock says are supposed to be better) and I jumped many times and so did Ron.
Tight acting, taut pacing, claustrophic settings and a great understanding of being scared of the dark.
Advance word from Matt: Snakes on a Plane is awesome and hilarious.
Advance word from Rebecca: Pulse sucks and rent the Korean (or Japanese) original instead.
