Lucio Fulci - the Maestro of Gore

Lucio Fulci is a favorite among horror fans for his slow, grueling and gory death scenes. Few have matched him in the gratuitous violence department. He made four films that feature zombies in them, three of which have a Lovecraftan quality and are soaked in atmosphere.
Those four films are:
Zombie (or Zombie 2)
The Gates of Hell (City of the Living Dead- international title)
The House by the Cemetery
The Beyond
If you are a zombie fan and have not seen these movies, I strongly suggest giving them a look. If you have seen them, how do you feel about them?
