The irony of living life in search of its meaning amidst inevitable death.
The series was never really about science, robots, conflict, retribution, or anything else that it may have featured. I wouldn't say any more, as I'd like for others to figure it out themselves. (I've hinted quite a bit anyway) :roll:
I'd say that I've truly enjoyed it til it lasted. The series had its ups and downs in the animation department (in a consistent level) and story-telling/development wise but it did manage to convey its point across with simplicity. A nicely crafted series nonetheless, way to go MadHouse! It's not the best that they could offer but it's still worth a watch. :D
Tbh, everything went the way I had expected it to turn out; especially with Ringo turning into an adult. Awww, she's so adorable even with the passing of time. :D
