I rarely give a 9/10 but this show deserves it. This is an adaptation of an arc in Astro Boy, with Naoki's twists and changes, it became one of the best told story of this year if not in all time. It follows Gesicht, a German robot detective attempting to wrestle his career and his personal life and when a murder case whose suspect is a robot, all hell breaks loose. (It's a bit cliché as cyber murder plots go, but it's nothing unforgivable). It also features Astro Boy/Atom and the other popular robots as they realize they have become more and more human and as they realize what emotions and feelings feel like. The second robot has the most emotional story among them and I loved it, without spoiling anything. Although Gesicht's, the titular Pluto's and the others come close as well.
Excellent adaptation and animation. As expected from Mr. Naoki. Hope more of his manga is animated in the near future. (Waiting for 20th Century Boys and Asadora!)
