This is neither the masterwork nor the garbage most people see in it. Sure, it has a lot of very strong points - Kinski's acting, a fascinating plot, the original settings, some good cinematography and an unforgettable closing scene. However, the movie seriously suffers from awkward cuts and terrible dramaturgy; and, worst of all, the stiff dialogues and the amateur-class acting of almost everybody besides Kinski (you will note both especially if you speak German) make some scenes unbearable. So all in all, while it may have the potential to be a really great movie, it delivers only sometimes, and in order to call it a masterpiece, you would have to be very generous and overlook many flaws ...
