This is another of those films where the director has a thing about his leading lady. Not that I object either to Miss Kinski but, if you take her out of this film, you're left with a creepy young fella and man with bushy eyebrows.
There is a plot which is revealed almost at the end of the film. There are plenty of shower scenes, a lot of running, poor editing and a useless script.
Other than that, it does pass a wet evening when you should have been having a barbie. Actually, even a wet barbie might just be better than this film. But I still like Nastassja Kinski. She also reminds me of her dad who similarly starred in strange films but, usually, ones which were rather more demanding than this one.
