Part of the DCAU (see Batman: The Animated Series). Well, anyway, the famous group of superheroes work as a team. Batman, Superman, Flash, Green Lantern, Wonder Woman (who we like), Martian Manhunter, and Hawkgirl (who we like). I suppose they still do alot of stuff by themselves, but of course that's not what this show is about. It's about them working together. At first I thought it wasn't quite on the same level as Batman or even Superman, but some episodes were really quite good. In the third season, the title changed to Justice League Unlimited (DVD site; Wikipedia), as many new members were added to the League, and an interesting new story arc was introduced, about Project Cadmus, and the government covertly working against superheroes. And of course there would be other stories in JLU, as well. Anyway, the quality definitely improved, and caused me to raise my estimation of the series (or both series, if you prefer) as a whole. (Oh, and incidentally, of course we like all the women in the League, as well as plenty of villainesses, and other random characters....) I should probably say more about the series, I just can't think what.
