Maybe, maybe not. It's a good show but not something I think adults would get into unless it was done more "adult" with its supernatural stuff like Heroes or Moonlight
I'll see that list and raise it.
Avatar: The Last Airbender, Justice League, Justice League Unlimited, Teenage Mutant Ninja Turtles, Samurai Jack, Megas XLR, He-Man and the Masters of the Universe, Invader Zim, The Spectacular Spider-Man, X-Men: Evolution, W.I.T.C.H., Ben 10, Ben 10 Alien Force, Chowder, Spongebob Squarepants, Batman Beyond, Static Shock, Xiaolin Showdown, American Dragon: Jake Long, Phineas and Ferb, Fairly Odd Parents, Jimmy Neutron, Kim Possible, Foster's Home for Imaginary Friends, Grim Adventures of Billy & Mandy, Mission Hill, Home Movies, Transformers Animated, Teen Titans, Jackie Chan Adventures, Futurama, Venture Bros, Aqua Teen Hunger Force...
Whew... that's a mouthful. Looks like plenty of good shows for the 2000s to me. Most of my favorites are in there.
