I read a lot of Japanese manga and watch some anime, but the trouble with most of the anime is that it falls into various familiar formulae designed to appeal to teenagers and young adults. Since I'm an old adult, not much of the anime appeals to me. However this is one very big exception! If you happen to be interested in astronomy I think you'll find it very moving. Ditto if you often read post-apocalyptic stories in any form, and also if you've been doing any thinking about how life will be when robots routinely move among us. It's a little jewel, and I stillam having feelings from it the day after watching it.
