Director Mary Harron brought her spiky intelligence to I Shot Andy Warhol, American Psycho, and The Notorious Bettie Page. But her torpid adaptation of Rachel Klein\'s novel about female sexual desire, jealousy, death wishes, and vampires at a girls\' boarding school defeats Harron\'s talent for exploring darkness on the edge of kinkiness. Sarah Bolger plays a dull Everygirl trying to get through teen gloom. Inexpressive British model Lily Cole stares at a vampiric new classmate.
