This show must have left a deeper imprint in my younger self than I thought, as I remembered a lot of the characters which appeared in the final arc of this show.
So I did a rewatch of this using the Japanese version. I couldn't find a version with my native language which aired on tv so many decades ago, but I guess this way I get to see how it was originally made.
It holds up pretty well, better than a lot of other 80s cartoons. It's still very much an animation aimed at kids though, but one you wouldn't mind watching along as an adult.
The first arc is pretty much the story we all know when talking about the Wizard of Oz, it's the middle and last arcs which expand on the story which was completely new to me. Basically blew my mind as a kid, "say what, the story didn't end where it ends in the movie?!"
It's a fun cartoon for kids, and as far as kids' cartoons go, this is one of the better ones.
