The 2009 movie changed everything in dramatic ways once again (even though Dr. Tezuka was not directly involved in the changes). It almost seems as if he had no problem with modifying the particulars to the story, as long as the key issues and character personalities were kept intact.
Whether or not he intended it to be so, it's as if he created a group of characters and a story that could be updated, customized and modified indefinitely. The issues certainly haven't become obsolete - and one of the fascinating things for me is to read the fan fiction that depicts the characters as today's youth (rather than the 1950's ideal) -- Astro is just as engaging now as he was a half-century ago.
Maybe that's because his creator kept imbuing new life into Astro's story and personality -- and he has left us with the invitation to continue doing so. Can't say I know of another character like this - and perhaps that's why I feel Astro's "best days" are still ahead of him!
