The Year we Make Contact
And 2010 is nothing compared to 2001, in any respect.
2010 has a many issues on the film-making side. Story is not one of them though, as it approaches the events of 2001 the same as the non-book reading audience: What the hell happened? It achieves that, but unfortunately takes a story that began as a work of art and turns it into just another sci-fi film.
All that said, the scenes of Jupiter on Blu-Ray are absolutely amazing to see.
In any respect 2001 was pretty weird, not that it makes it a bad film,
Let's start here: Stanley Kubrick, at your current age you know what you are getting yourself into. The film and movie were created side by side with the intent being that the audience experience both. Unfortunately, the book didn't make it on shelves before the movie came out, so theater audiences were left to figure it out on their own, in an age before we landed on the moon or the concept of aliens being responsible for man's origins was in the public mindset.
Not random at all. Kubrick does a good job of leaving the audience with the same information as the humans in the film. It appears random, but when you analyze it and what it is actually doing, it is anything but.
a computer that kills people
Kills people because it follows its programming in the strictest way possible. This is one of the oldest clichés in science fiction. We can thank Asimov and Clarke for laying a foundation of caution to all future roboticists.
and whatever the hell you'd call what happened at the end of the film isn't exactly in the realm of what I would call a normal occurrence.
The end of the film is the tricky part. Think of it this way: It was first contact with an intelligence that was, millions of years ago, beyond our ability to comprehend today. So intelligent that they created intelligence in us. That contact would not be anywhere close to what we call a normal occurrence, and any outside witnesses would like refer to it as "whatever the hell happened there." This is the one part that many people need the book to explain. Kubrick only had a few minutes to work with here while Clarke had an entire chapter
Seriously, if the story intrigues you at all pick up the book. Clarke explains it as he goes along instead of pummeling your senses with images of stuff that requires you to stop and think.
