“The Witch Files” (*1/2 out of four) was a bewitchingly bad brew of high-school cliches about a group of teen outcasts (Paget Brewster, Holly Taylor, Valarie Mahaffey, and others) who form their own coven and start performing increasingly alarming spells for those who get in their way. Made only for those who have never seen “The Craft” but this film lacks both that film’s craft and cast and runs out of steam (and story) pretty quickly. Big special effects showdown is a big bore.
