To me, Batman TAS is second best to Gargoyles. If anyone hates Gargoyles, let's just say we're better off not knowing each other.
Batman: TAS is probably the greatest comic book series ever. Superman and Justice League are entertaining on their own ways and Batman Beyond put a stylish new twist on it, but nothing can ever top the original Batman. And it could be argued that Mask of the Phantasm was the best out of all the Batman movies (besides Batman Begins).
It was one of those shows where the people knew what Batman should be like and really went with it. :)
Gargoyles was great too. It was a very surprising move from Disney, but it shows how much the studio wanted to try new things.
I found the animation quite above par on the other Disney cartoons. Then I realized that all the animators were Japanese. But it's still a great show.
As for Batman: TAS, it was a rarity. For one thing, it didn't contain any comic relief or lighthearted moments like you got in many other shows at the time. It also showed bullets, something that many TV networks refuse to have in cartoons (they would often be replaced by lasers or other types of weapons). One of the rare early 90s cartoons that adults can enjoy fully.
IMO, as far as action cartoons go, its only competition is Superman, Justice League, Gargoyles, and Beast Wars. And it's still the best of all of them
what about the spiderman, xmen, the incredible hulk, iron man, and fantastic four cartoons of the nineties...personally i cant pick
