Some of you can rile on how 2001 is "bad" and you're entitled to your opinion. I disagree with it, but I'm not going to try to convince anyone to like anything they don't.
Yes, 2001 isn't about the dialogue, and why should it be? Kubrick was a photographer first and his films tell much of their story via the composition of the frame. 2001 gave him the opportunity to take that to extremes that more traditional film narratives didn't because it's about things that aren't plot per se.
And anyone who's judging Kubrick's work on the basis of 2001 alone is missing out. You should at least see Paths of Glory
and Dr. Strangelove. Strangelove
alone is about as black as black comedy gets.

Major Kong: Well, I've been to one World fair, a picnic, and a rodeo, and that's the stupidest thing I ever heard come over a set of earphones.
