You need to see the original Nosferatu. It's fantastic- really a fantasy, like a bad dream. It's like a nightmare. It's from 1922 and a silent, but I THINK the original vampire film. There was another one made in 1979, but it is not as good as the 1922 version (but still good).
I loved the original Noseferatu I THINK it's German expressionism, but could be wrong about that, it's been a while since I read about film.
