Watched this for the first time last night on Blu-ray, being a fan of both Italian horror and giallo movies and of Klaus Kinski I looked forward to it. The film looks pretty good, the early 20th Century costumes and sets were nice, there is a decent amount of gore plus plenty of nudity. I liked the musical score too though not sure that it matched the time period of the story. There is definitely some of Poe's story The Black Cat present, plus I felt Don't Look Now (1973). We get two creeps, not just Kinski (who's part sadly ends far too soon for my liking), but also Lucianno Rossi who plays a hunchback with a very unhealthy love interest in his own sister. I would go as far as to say he out-creeps Klaus in this movie. What let this movie down for me is the plot, I found it hard to fathom out what was actually going on. I will give it another chance, perhaps going for the Italian language option.
