Nothing

I love this film for various reasons. The gore is top notch, in terms of both its explicitness and the quality of the FX, the atmosphere and music are good, the stories are interesting (even if they are in German you can work out what is going on). For a film with such a low budget (essentially an amateur effort), Ittenbach has worked miracles putting together such an original, creative and imaginative film. Personally I wish more horror films were like this, rather than the sanitized Hollywood crap we've been forced to endure for the last decade or more.
