What a terrifying film. My only problem with it was that the build up went on a bit longer than I felt it needed and that the slightly off humor early on was a tad, well, off, it did fit with the overall psychotic theme though. Quite intense. It really drags you in. Really strong and scarring performances from both Carstensen and Böhm.
