12 DAYS OF HALLOWEEN!
The scariest thing about the original is just the look of Max Schreck's Nosferatu. You may say his exaggerated features make him look too non-human. But I think Schreck's look is the best thing about the original. Klaus Kinski's Nosferatu in this remake is still scary looking, but his appearance is toned down considerably. His eyebrows are less out of control, his ears less exaggeratedly pointy, but he is still a scary looking vampire. His at least reasonable proximity to a man does give him room to seem closer to the human species than the original. But not by much.
Additional casting notes: I recall on the commentary track for the movie Fitzcarroldo, how director Werner Herzog talked about how difficult Klaus Kinski was to work with. It should tell you about how good Kinski was that Herzog would keep using him in film after film. He is a marvelous and intense Nosferatu and is great to watch on screen. Extra hazard points to director Herzog for being able to rein in this difficult thespian here and elsewhere.
The movie also benefits from two strong actors in the roles of Jonathan and Lucy Harker: Bruno Ganz (later my all-time favorite Hitler in Downfall) and Isabelle Adjani (two-time Academy Award nominee.)
