I think the topic is quite clear, but you can see I'm a regular on these forums so I'm smart enough to explain further.
Talk about any movie that's:
1) Weird. This can be a very interesting way of filming or a totally messed up story.
2) You enjoyed. We're not here to discuss crap, we're here to discuss good crap.
I'll start with 2 examples.
I quite liked the movie Dogma . The story is completely ridiculous and some of the actors are really messed up, but it's a fun movie and actually surprisingly deep.
And of course you can't talk about weird movies without mentioning Sin City. The way it's filmed and the story are extremely complex and at times hard to follow, but in the end it's an amazing story once you get into it and it's a unique movie.
