Roger Ebert's latest thumbs up:
I was never, ever bored by "Cloud Atlas." On my second viewing, I gave up any attempt to work out the logical connections between the segments, stories and characters. What was important was that I set my mind free to play. Clouds do not really look like camels or sailing ships or castles in the sky. They are simply a natural process at work. So too, perhaps, are our lives. Because we have minds and clouds do not, we desire freedom. That is the shape the characters in "Cloud Atlas" take, and how they attempt to direct our thoughts. Any concrete, factual attempt to nail the film down to cold fact, to tell you what it "means," is as pointless as trying to build a clockwork orange.
