A spare, creepily atmospheric ominous thriller with a death grip on the psychological aspects, Bryan Bertino’s brilliantly suspenseful directorial debut is enormously unsettling. Returning late from a wedding reception, Kristen and James pull into his family’s South Carolina lake house for what was supposed to be a romantic night. But she's just turned down his marriage proposal. Their fragile relationship in the light of her refusal heightens their vulnerability later when a strange girl pounds on the door at 4 o’clock in the morning asking for someone who clearly doesn't live there. Slowly and steadily, the situation escalates: a few more knocks on the door, some disturbances from inside, and finally, the appearance of masked figures emerging from the shadows. The couple’s worst nightmare has just begun… An all-too effective nerve-jangler, with stars Scott Speedman and Liv Tyler credibly registering every nuance of panic, intense horror doesn’t get much scarier.
