DVD: Paranormal Activity

This zero-budget horror film scores high marks for its ingenious costcutting. It's all shot on video camera within the four walls of one house, the pretext being that a young Californian couple is being haunted by a demonic spirit, and the boyfriend is documenting proceedings(and no, there's no point in their moving out, because the demon follows the woman wherever she goes). It's not terribly frightening, but it's intriguing, slick, and engagingly acted by its unknown stars.
