Watch the Phantasm series. The first one especially. The rest are kinda up and down but there's some good parts in them.
Nosferatu is on Netflix Instant Watch.
Seems like people have forgotten a lot of the zombie movies. I actually like the remake of Dawn of the Dead (I think that's the right one), and the early ones are also pretty good mostly (the one that takes place at the farmhouse is one of the better zombie movies).
There's also a bunch of Tales From The Crypt and Twilight Zone type shows and movies that have several little tales. Peter Jackson has some Evil Dead-ish type of horror movies. The X-Files makes for pretty good Halloween watching I think too.
Oh, and I almost forgot John Carpenter. Halloween, The Thing, They Live, Prince of Darkness, and even Big Trouble In Little China.
Leviathan was kinda cool. Alien and Aliens are good.
Dead Snow.
Fright Night.
