I wish I had seen it as a kid. It really has a lot of depth in it, a lot of empathy. Self-sacrifice. Not showing the world as good/bad but as the complex system it really is. Not giving up. A lot better than your average saturday morning cartoon. Kids need to learn these things (not by watching cartoons necessarily, that's just the carrier), or they might end up as adults with a too simplistic world view.

Of course, for the younger children, Spirited Away might be a better choice. And Totoro.

naruto never gives up.
