For the first hour or so, a taut two-hander that mostly plays out on one set, with David Hyde Pierce giving one of his best performances.
Problem is, the director/co-writer gives this one too many twists, which ends up robbing it of some of its power. Still, fun for anyone that likes Hitchcockian thrillers.
Great psychological thriller. Just when you think you have it figured out, you don't. The transition of style and story during the last third was very awkward, but it's worth it seeing how much deeper the story gets.
