As a fan of the 80's series & Tezuka's original comics, my first impression of this show was not a good one. I bought this for my young son but decided that, despite being less violent, it was too flashy & fast paced for his young mind. This new version doesn't have a fraction of the 'heart' that the older series' had... and they've changed so much it's hard to trace much of what you see in this show back to Tezuka's work. I think the english dub/edit is to blame for most of this and would very much like to get my hands on the original japanese version.
However, this show does have its strenghts, namely some absolutely top notch art, animation, colouring, action, and some interesting storys... this is the only Astro Boy story that actually has a long continuing story (discounting the Atlas vs Astro arc from the 80's version of course), and though I haven't seen all the episodes, I'm eager to see how I'll feel about this series after I've seen how it ends. It's actually quite a good show if you can manage to enjoy it for it's own merits, as opposed to comparing it to the old show.
I would reccomend this for kids around the 11-17 year range... Younger kids would get more out of the 80's series & I think Adults would appreciate it more too. Of course it's a must-have for hardcore Astroboy/Tezuka fans!
