I still haven’t seen it yet so I’ll reserve comment on that, but there is a Japanese children’s cartoon that I really love called Oden-kun. The first episode heads this entry.
It’s not one of those ironic, winking-at-the-adults shows; instead, it’s sweet and earnest. (Although the super-long intro in this episode is weirdly dark.) Oden-kun just has a quality to it that always makes me smile, and I’ve met other adults in Japan that felt the same way. I suppose in that sense it possesses that rare quality that Peanuts has, in that it could be enjoyed by nine year old girls or 34 year old cartoonists.
