I saw it this weekend with a group of friends while I was out of town. I was excited about the movie and skeptical about it at the same time because it and 'High Tension' share the same director and 'High Tension' was absolute crap... But 'Hills' had such an awesome trailer I couldn't pass it up.
So more on the movie, it's more than I was expecting, a lot more. Its a bit more 'brutal and unflinching' than I was expecting and I have no idea how they got away with the R... It's not big on story, but they highly succeed in making you absolutely hate the Hill people and the movie is beyond tense.
If you're going to bitch about being "poor" and "how you can't get out to see this", you're really missing out. Word up to IDE, this one freaks chicks out.
One more thing, the 'Silent Hill' theatrical trailer looks beyond stunning on the big screen. You also get to see a teaser for 'The Omen' remake, unfortunately the kid they got to play Damien looks like a turd-wad.
