What makes this movie worth watching, and I would say it is indeed worth watching, is the way it zips in and out of its protagonist's mind. Scenes constantly veer off into grim fantasy sequences, but you often won't realize it's fantasy until it's over. One of the things books do better than movies is to get inside someone's head, but here you really do get pretty far into his paranoid fantasies and death obsession.
The movie is not, for the most part, a horror movie, but it does manage to generate suspense by bringing you into Alan's paranoia. The movie is weakest when it is most horror-movie like, and the last half hour feels way too much like an episode of the Twilight Zone (and even more like its wannabe cousin The Night Gallery). A stronger ending would have made for a better movie, but this one is still interesting. I give it a low 7.
