Maybe not the best, but give me Devil's Rejects and House of 1,000 Corpses.
I can't stand any Rob Zombie crap. Especially that abomination of a Halloween movie.
I was a big fan of the Nightmare on Elm St movies. A bit cheesy, but man Freddy was an awesome character. Not only did he kill you in your dreams, but he screwed with your head while he did it. I like Jason and Michael Myers, but the silent but deadly just isn't as good as the smarta$$ killer.
Zombie (not Rob) movies are my favorite. I like all of the (Living) Dead movies (Night, Return, Dawn, Day, etc) and some of the newer ones aren't bad (a couple Resident Evil's, 28 Days/Weeks Later, World War Z, The Crazies).
There aren't very many actually scary movies anymore though. Mostly they are more action than horror. I love a good scare, but nothing hardly does that like the older 70's-90's movies.
