I read the book, 2001, but couldn't get past the first 10 minutes of the movie. Kubrick was a nut. 2010 was more in keeping with the book.
Good, I'm not alone in the 2001 versus 2010 battle. For years I kept a VCR of 2010 copied off of the late night movie before we had infomercials. 2010 v. Sunshine?
Oh, you are not alone.
2001 (and in turn Kubrick) is one of the most overrated films (directors) out there.
It is boring beyond compare. The visuals are fantastic but other than that it's utter crap.
I had the same opinion about a decade ago. I enjoy it very much now, but I can see why others might not.
