I'd give it a 9, simply because the way it was filmed, the very solid storyline, and the gore. The movie also seemed very fluid, everything fit in without wandering off onto random tangents. Just don't bring a kid to this movie, because I think they'll either a)be traumatized and end up throwing up popcorn because of the gore, b) absolutely love the hardcore blood, or c)end up being one of those Columbine shoot-em-up kids.
