Batman the Animated Series is by far one of the most regarded animated Superhero shows of all time. Creators Eric Radomski and Bruce Timm treated the source material with respect and created a show about The Dark Knight that would stand the test of time. But the real reason this show succeeded as well as it did is all due to the Villains. Without The Joker, Harley Quinn, Poison Ivy, Killer Croc, or Two Face the show doesn't see the success it does.
