Superman TAS was excellent. Easily the best version of the character on the big or small screen, and he was similarly excellent on the DCAU's Justice League.Disagree simply because I am a total slut for Batman the Animated Series. I adore what they did for Two Face/Harvey, Mr. Freeze, and of course the creation of Harley. Plus Mark Hamill as the Joker is probably the most iconic thing ever (so is Conroy but I'm pretty sure he played Batman in Justice League just because he had to)
But I might also be biased against Justice League cause I watched Super Friends as a kid before school and got mad that Superman did everything which made me pretty much hate all things with him in them minus the Christopher Reeve movies. But the Animated Series is still absolutely fantastic
The episode where he faces Gilbert Gottfried's Mxysptlk alone is better than any of the Superman movies ever made, and it's not even the best episode of the show.
