Hell yeah, I'm actually rewatching it right now too. I never appreciated how amazing the aesthetics of the show is when I was a kid, they have a great mix of gothic, noir, and art deco that I haven't seen any other Batman media capture since.
And it didn't really pull any punches. The whole thing can get real dark, especially for a kids show.
How's Superman: The Animated Series? I want to try that out after this.
