I read the whole thing, and was going to re-read it this summer - have put this off until I have my eye surgery next month (cataracts)
I noticed how realistically human the robots were, too, but I took this to be Urasawa's idea of how Tezuka might have updated the appearance of the characters. If robots and humans interact almost seemlessly it would make sense that we might physically blend in together.
What was most "surprising" to me was the way Pluto took over the "off hours body" of the construction robot (who was the "Pluto" that Uran befriended).
Epsilon just made me want to hug him - he seemed to want to fight Pluto off, but not attack and destroy him. The way his hand saved Wasilly just broke my heart and made me cry!
What I loved so much about this adaptation is that Urasawa gave us a chance to care about the OTHER great robots of the world - not just Astro. The whole story, really, is about the incredible power of love and peace . . . and the tragedy of what happens when hatred runs rampant.
It was pretty wierd reading "backwards" but I did get used to it!

I really can't wait for the movie, and I hope Urasawa creates another arch from Astro Boy. I'd love to have him retell the origin story.
