Interesting story which I'm sure will be developed in the sequel. Likable characters. Some of the usual high school cliches could have been left out. Great action the last 30 minutes.
I think the film looked great, had enough suspenseful moments to keep me jumping and didn't take itself too seriously. Enough blood to keep the horror fanatics happy without completely grossing out the rest of us. It gets right into the story and keeps the pace up for the duration. One of the better of the more recent scary movies. Not too cheesy or cliche.
