Can anyone recommend any good horror movies on instant Netflix?

Answer 1

The Human Centipede, The Signal, Dead Alive, The Evil Dead, Ichi the Killer, Audition, Night of the Living Dead, In the Mouth of Madness, Tales From the Hood. Most (if not all) of the Masters of Horror series is also on Instant Watching.

Here are some that I've heard good things about, but haven't actually seen yet: Kaidan, Crazy Eights, Train, Let the Right One In, Dance of the Dead, Boy Eats Girl.
