I remember watching random episodes on adult swim 20 or so years ago and thinking it was cool, but damn, I didn’t realize this show was as interesting, deep, and meaningful with characters who grew or developed with such novel time appropriate scifi or western plots.
So it wasn’t just a theme song after all.
