This is a decent budget, nice, crisp looking movie. Which are qualities I happen to like a lot in horror movies. The actors do their job, nothing special but alright, the effects are good, pacing is pretty solid.
Unfortunately it's nothing special really, it does it's job pretty well, but nothing exceptional. I was kind of waiting for it to "take off" a little more, which it never really seemed to. Had it gone the extra mile, so to speak, it would have been a clear 8 for me.
To sum up: Decent flick, looks nice, good party-factor, some nice gore, couple of laughs, absolutely entertaining.
