Taking an early Astro Boy story by the great Osamu Tezuka, writer-artist Naoki Urasawa reimagines it in a way that echoes Alan Moore's reinvention of Marvelman/Miracleman back in the 1980's.
The premise is the same as the original -a near-future world where humanity is assisted by robots that look like robots and also robots which are indistinguishable from human beings: Gesicht, our detective hero hunting what may or may not be a killer robot, is one of the latter. Stylistically, Urasawa draws in a distinctively low-key realistic manner as opposed to the wild cartoonish manner of Tezuka's original. Neither is Urasawa the writer in any hurry to rush his story, rather it is told sedately, lingering over character, drawing out and focussing in on emotional details which resonate with the reader and it isn't until the end of this first volume that we, and our somber hero Gesicht, finally meet the protagonist of the original story.
This is an extremely impressive opening to this series and if succeeding volumes match it then I'll certainly be around until the end.
I would also recommend this, because of its clear, accessible and unfussy style, as an excellent start for anyone who hasn't tried manga before, though it isn't suitable for, and neither is it aimed at, children.
