Where can I discuss movies online?

Hello,

I'm looking for an active message board/forum/community/etc that focuses on the discussion of film.
Not too dumb. Not too pretentious. Basically, a place where one could get into good discussions about movies new and old.
I've tried some searching without much luck. Please tell me about the fantastic forum I've missed.
And if it doesn't exist, does anyone want to start one?

Please help.
I didn't find the right solution from the Internet.
