This has to be one of the best serial killer films if not for the camerawork or editing (much better than Buttgereits previous stuff) for its deadly realism. The special thing about this one is that it doesn't depict - instead it forces viewers to see from the killers eyes and think the killer's way.
Moreover, and mainly because of the obvious improval of the technic (it LOOKS much more professional than, say, Nekromantik, even if it's not, and I know because I watched the special edition where we see how they filmed this thing) , this film might appeal to other people as well, apart from sickos and people on weird / gore films.
I can imagine that some serious cinema-lovers could take this very seriously and consider it a great film as it is.
