A collection of some pretty old sci-fi stories (from 1968-1973) created by Osamu Tezuka filled with dystopian elements. Most of them are pretty interesting. However, with everything that we've been through the past years, a few of the stories can be quite believable nowadays (not that this is a bad thing).
As far as the art-style is concerned, I have some mixed feelings. It lacks a lot of details, especially in the design of the characters, but, on the contrary, they help create a fitting and creepy, at times, atmosphere that suits perfectly with the theme of the stories.
