Hard pass!  For my money, Batman, The Animated Series was far better. 

The character development, from Bruce Wayne, to the villains he faced as the Batman, to the challenges he faced as the Batman, himself, was excellent. The animation was smooth. The plots were full.

 I think this show was too deep for me as a kid. I bounced right off it, but I ate up Batman Beyond.  

 No harm in trying again as an adult!  It’s on Amazon. Beginning with the first episode, it jumps right into moral ambiguities for the audience to consider.
