I like this anime, because I think that it's in perfect Osamu Tezuka's style. The graphic is modern and the story has been unpdated. The story is really amazing and I love the 'humanity' of the protagonist, 'atom' aka 'six'. You can find his evolution during the entire story and I suffered, like Ran, when he was under repair. Ran, the little sister of Ochanomizu, is really interesting, a shy and cute girl with a great love for robots. She is a robotic true genius and probably could be more intelligent than her bif brother. Being this a modern anime Ran stands out among many anime dominated by tsundere girls. Thefamily who grows around him is lovely and 'six' is a good and true hero.
The two young doctors are great.
It's a pity that only the first volume of the manga has been animated.
