Ok since noone else has replied I'll step up to the plate...I'm not a fan of the gore-y, torture porn stuff so don't kill me for that. To each their own..
I would say "Carrie", "Planet Terror", "Repo the Genetic Opera", "Interview With A Vampire."
And maybe this does'nt really count but I loved "No Country for Old Men", "There Will be Blood" and other films like that.
I don't know that "No Country for Old Men" could be considered horror, but it scared the hell out of me. I don't do horror either, really. But my fave would be the "Saw" series. And I don't even care that there have already been 349028409 of them.
