The movie is perfect in it's scenery, weirdness and darkness. However the script is not focused enough, so as a viewer I struggled to pay attention. Come to think of it, maybe that's intentional. The whole experience seems in retrospect like a bad dream. Unable to escape the sanatorium, the main character might as well be having a nightmare. There are some especially memorable scenes that will stay with me. I also might think differently about eels in the future. I hope I don't have to go to a sanatorium anytime in the near future. One where they try to cure wellness would really be a nightmare.
