I actually did see the show a handful of times, back when it was actually on-air. I remember virtually nothing about it. Hey, you remember those other MTV shows? Like that one with the guy with the giant head and something about aliens? I don't know what that was.
The first time I saw Aeon Flux, it was something like 4:30AM and I had absolutely no idea what was going on. It was definitely a trip.
And yeah, I remember "The Head", from "MTV's Oddities". I think that's what they were called, anyway. The guy had a little purple alien dude living in his skull.
It's amazing to think that there was once a time when MTV was actually responsible for pushing the creative envelope rather than holding it back or shoving it through the shredder.
The Maxx was an impressive show, and made me immediately seek out the comic book and read it from start to finish. It was even better.
From the most current shows, I don't know. I think Adventure Time and The Marvelous Misadventures of Flapjack are awesome.
From discontinued shows, Gargoyles (pre-Chronicles) was nearly as good as it got. I don't remember a single show ever that was better than that one (the original Batman TAS came close). And I've watched a lot of shows. If you haven't seen it, GET IT NOW.
A question aside, was Batman TAS officially part of the DCAU universe? it felt really out of place with the art style of Superman and the JL, and REALLY different from The New Batman Adventures, which actually felt a better fit with the other shows. To me both shows always stood apart.
A bit of an oldie, ReBoot was really good. Probably one of the first fully CG TV shows.
Ahh... the D&D cartoon... a great example of awesome potential ruined by the moral guardians. Remember,
The Complainer Is Always Wrong (not a link to TVTropes, btw).
