A nice showcase of Tezuka's art style in an animated film. The plot progresses fairly quickly, leading up to the climax. Some of the rooms and animations are very impressive. I distinctly remember the room with the giant robot fish, and the tall escalator some of the rich guys come down. You also get to see some worldbuilding where you see what various robots are being used for and doing. The only bad point about this is it's over too song. The plot builds, the climax happens, and then you're back to square 1 basically. But I guess that's better than taking 23 episodes to do the samething.
