Certainly not worth all of the hype this movie has generated. Unless you're an idiot high school kid, I don't recommend this movie at all.
It took until the last 25 mins or so for this movie to become interesting. Sure. there were some strange things going on, but not as interesting until the last segments of the film. It was very slow to get to the point. The smart-a** boyfriend and the last scene were the only two things from this movie not totally sucking a fat one.
Save your money or go to a matinee. I cannot wait for this stupid movie's hype to die down. Just like Blair Witch Project, this movie fails to live up to the expectations of being a classic horror film, like its hype is making it out to be.
