Writer-director Oren Peli's ultra-low-budget thriller has the single-camera format and reality-blurring promotional rollout of The Blair Witch Project and last year's Cloverfield, yet it distinguishes itself fairly effectively.

The movie recounts three weeks in the lives of Katie (Katie Featherston) and Micah (Micah Sloat), captured on the video camera purchased to record the unexplained and increasingly forceful happenings in their San Diego apartment. Since most of the activity occurs at night, the camera's left on as the young couple sleeps.

Tension is enhanced by the repetition and subtlety of these scenes, the film's creepiest, while Featherston's sympathetic performance sells the supernatural premise. On the other hand, some trimming wouldn't have hurt this, and in Micah, Peli has an annoying character that acts like he's never seen a horror movie.
