What are some good horror movies?

Dead Alive, directed by the same guy who directed Lord of the Rings(but it's nothing like Lord of the Rings I mean it's a horror film :)), Evil Dead series, they're all awesome. Planet Terror, directed by Robert Rodriguez(Spy Kids, Once Upon a Time in Mexico), The Thing, The Abyss, The Devil's Backbone(Directed by the Guillermo del Toro[Pan's Labyrinth]). I love horror movies when they're done right.
