This cartoon, aimed at kids back in the 90's who were aged 9-13, dealt with persecution & prejudice, the Registration Act, childhood abuse, love & relationships among adult characters, and even featured a character physically being killed (something unheard of in cartoons). You could even extend this to Gargoyles & Batman: TAS.
And now today, for that same age group, I can't even think of a cartoon in the last 5 or so years that even came close to touching on these themes and subject matter. We have dipshittery like Steven Universe or Paw Patrol. And most of the superhero cartoons have been given either crappy, stringy animation to make it more childlike, or glossed over with a "mini" or "youth" version.
