I always have trouble with categories. I'll just throw out a few ideas of awesome films that I think people should have seen:
- Lock, Stock and Two Smoking Barrels -> best intertwined-stories-movie that I have ever seen. And it's humorous in its own way as well!
- Any western movie directed by Sergio Leone -> Best Western movies in existence. Period.
- Avalon (directed by Mamoru Oshii) (And no, it's not a typo of Avatar) -> If I explain why it is awesome, it takes away from its awesome.
- The Terminator, The Running Man, Tron, Robocop, (there are more) -> These form a nice "time-document": this is what people were afraid of in the 1980's.
- [rec] - scariest zombie movie I have ever seen. Think Blair Witch Project with zombies.
- Shaun of the Dead - Funniest zombie movie I have ever seen. It's a romantic comedy, with zombies. What more do you want?
- Anything by Quentin Tarantino -> my favorite movie director. If you don't agree, you are wrong :p
- Ben Hur -> No really, this is actually great, especially if you consider its age!
- Romper Stomper -> I like this more than American History X.
- Enter the Dragon -> no explanation needed.
- Ong Bak -> Awesome martial arts movie. It turns out Muay Thai translates to the silver screen even better than Kung-Fu. And it has a great car chase variation, with Tuk-Tuks!
- Bullit -> Speaking of car chases... For a more modern car chase movie, you could get Ronin, but I like Bullit more.
- Amsterdamned -> It'll be tough finding a subtitled version, but this has a better boat chase than the one from James Bond, in my not-so-humble opinion.
- Guesthouse Paradiso -> Rick Mayall is a personal favorite of mine.
This should keep you occupied for months...
