Underrated
I've heard nothing good about this movie, but it does accomplish some things. I watch a lot of horror, and there's too many movies that take forever to get scary, tell bad stories, leave ambiguous ending, or just don't explain a damn thing.
This movie made an effort to be clear. It got to the point with suspense and horror (a little low on that, tho), moved at a pretty decent pace, and was surprisingly hilarious a few times. I think it's worth watching.
