I just saw this critically acclaimed sci-fi masterpiece last night with a bunch of friends and we all concluded this movie is cr*p. I must give the film some high regards for its musical score, carefully done space animation and cool special effect (amazing given that it was filed in the 70's). The movie however, is tedious, confusing, boring and overly slow-paced, not to mention it didn't even have an engaging plot. The acting was awful. The best performance was actually by the computer HAL whereas all of the human characters were bland and uninteresting. I thought the first part with the apes was not only too long but also stupid. A bunch of apes jumping, shrieking around a monolith, yeah that's very profound! Very other scenes in the movie were extensively long and drawn-out. Who wants to spend 5 minutes seeing moon shuttle in transit or the guy going through star-gate (or wormhole)? Maybe the director was trying to communicate a sense of the grandeur and hugeness of space, but he failed to do so.
