I just finished watching this for the first time a little while ago, and I have a new movie to add to my list of favorites. I loved every second of the movie. Each story on it's own would have been a really good movie, but add them all together, and you got something amazing.
I was going to try to pick a favorite story, but I can't.
One of the things that I thought was great was something that I didn't actually pick up on until the end. Each of the actors characters all represented the same concept in each story. The two biggest being Tom Hanks always being a guide of some sort who lead the main character to where they were supposed to be at the end, and Hugo Weaving was always a representative of the order that the main character always rebelled against.
