Anyone that either doesn't understand this or found it too slow is just that: too slow. The movie is great!!! I'll explain the movie to those that don't quite get it.
Starts off with early man. One of the tribes is dying. They have no food, and another tribe even fought them off from the only water hole. Life sucks for these guys. To make matters worse, they're getting eaten... no even the top of the food chain, yet.
Then, one day, this... thing, this monolith appears. Out of nowhere. Well, aliens gave early man this to teach them. You see, during parts of man's evolution, these aliens were there to guide us. At points of our evolution, they would give us a guiding hand, making us better than what we were. So, the monolith gave man the knowledge to use tools. Now man thrives, and is doing well. One very big thing that he showed was early man did well because of the monolith. And, then it left, but it had done its job. It gave us what we needed.... but it was man that used the tools for evil (killing the other tribe members). And it was shown for a fact that the monolith wasn't there, and it was all man's idea to do that.
Now, in the year 2000, the first thing you see is a nuclear satalite. Great transition from the bone to this, as it shows man's still fucking up with weapons. Anyhow, man's evolution is about to take another leap. On the moon, near Clavious, an object had been found. It was buried millions of years ago, waiting to be found by man. Man did find it, and it sent a transmission going to Jupiter. 18 months later, we go out there... to see what it is that the aliens want us to do. Well, no, not really.... just to see WHAT this thing is.
5 men and a super computer go on this mission. Three of them were asleep, while two others, Dave and Frank, have no idea what's going on. Hal 9000, leads the missiong. "No 9000 has ever made a mistake... " The computer is pretty much perfect, and that's where it goes wrong. So perfect that HAL feels that the humans will jeapordize the mission, and so it tries to kill them. It lied to them. It killed them off one at a time. Dave, the last survivor, pulls his functions. How will he get back to Earth? No idea. He just had to survive. Here's where people get confused. The HAL side story is so deep that people think the movies about the computer. WRONG.
So, Dave finds about the mission's real purpose after "killing" HAL. He goes to this monolith, where he's changed forever. He, after a long period of time, is reborn into the next level of human. It's the next step of our evolution.
Taking out the fact that 2010 claims that HAL was told to lie and it confused him sort of throws the story around a bit. Also, in 2010, man's still fucked. The Star Child, David Bowman, is only an informer, and not the next step to humans that you would have assumed at the end of 2001. I think that 2010 is just as good as 2001, if not even a bit better. I love the idea that Jupiter turns into a second sun (called Lucifer, in the later books which weren't quite as good as the first two).
Anyhow, that's about it. Great movie that makes you think. It's drawn out slow for a reason. One of the few films that's brave enough to make space real. Space is boring. There's no sound in space. For when it was made, it was incredible. They didn't know about the moon landing when this movie was being made. Clarke and Kubrick had to give best guesses as to how things were, and they were so dead on before we even knew the info for sure. Great movie. Clarke is a true visionary.
