I didn't like it. The first hour dragged and the rest was your typical horror "scares." The theatre was only a quarter full and I didn't hear anyone scream, yell, jump or gasp during any of the scenes.
I don't want to spoil anything, but it's a horror film so you know they left a few unanswered questions at the end in case they do a sequel. It just wasn't very dramatic.
If you liked Texas Chainsaw Massacre and Wrong Turn you might like The Hills Have Eyes.
