Here's a sexy and bloody by-the-numbers supernatural teen horror film that somehow manages to be fresh and exciting. The tight and intelligent script is matched by high production values, interesting characters, slick special effects, and a haunting musical score. The direction is smart and generates a tense atmosphere of ever-increasing dread without dipping into cheap thrill exploitation. Highly recommended as a late night scare-fest - particularly if you enjoy watching girls dabble in the black arts.
