Well, I enjoyed Army of Darkness, John Carpenter's The Thing, Scarface, Fight Club, Dune (David Lynch-version), uhm...
Army of Darkness is a cult classic horror/comedy. You might also enjoy Evil Dead 2, the direct predecessor. Both extremely B-movie-ish.
The Thing is just great. Paranoia, snow, aliens. Very nice.
Scarface, do I really have to say anything about that movie?
Fight Club, nice little anarchic mind-boggery, if you have a slightly chaotic snese of humour, you'll enjoy it even more.
Dune, well, it's a cult-classic sci-fi flick based on the books. Of the two versions available, it's definitely the better one even though the Harkonnens are depicted a bit weird...
