Highly enjoyable teen horror movie, with a morality play at it's core. The first 2/3 are part high-school satire, part twisted buddy flick. However, for the last third of the movie the special effects and fight scenes are a bit much at times. Some of the witchcraft is more like a bad drug trip. I did enjoy watching Sarah go from meek and frightened to strong and righteous. The good guys are always more fun when they can throw a little lightning.
