There are worse movies rated better. Would have been amazing with more tension and real horror. The plot is good enough and the setting is fantastic for Kinski's character to journey into sickness but he never gets that sick or seems that mad in the environment. Even the voyeur and torture elements could have gone further. I like the creepy stillness of Kinski's character but in a movie that is about one character you need something else even if it's one or two short scenes. The female characters don't really interact in a way which produces more tension or horror against Kinski's character either. A missed opportunity. The movie does also have a climax which saves it. I'm glad I watched it and Kinski is good in it.
