Really dark, but a really satisfying ending. Part of me feels a little bad for Pau, the orderly, because he’s rather weak and ineffectual, but only a very, very, little bad. There are some very tense scenes, and a real race-against-time feel throughout that helps the suspense build. It’s not a masterpiece, but it’s enjoyable (at least after the icky beginning …), and it’s nice to see people get what they deserve.
