Okay so we're all agreed this isn't classic thoughtful film-making, however if you want a disposable slice of teen horror a la The Faculty [DVD] [1999] or The Craft [DVD] [1996], with attractive stars, plenty of gore, and some quirky performances (J K Simmons' turn as eccentric hook-handed high school principal is hilarious), then you'll enjoy this. The dialogue is often witty, the humour as black as pitch, and the special effects impressive. Grab a bag of popcorn, switch your brain off, and let it wash over you.
