Saw it last night and I absolutely LOVED it. Sure it "ripped" off other horror films, but that was the point. I think it was more of a parody of horror films then an actual horror film itself. That being said, I had a blast with it and my GF (who hates horror films) had a blast with it as well. Definitely a Bluray buy when it comes out.
the hand at the end was hilarious
I was like...wtf? I LOVE IT!
