As for cartoons... well... I can only say the only good shows are stuck on Cable. Spongebob and Fairly oddparent, I feel are well done, and hilarious. The New TMNT show, until the fast forward crap was pretty good, and even a few of the Dubbed animes were pretty good... until they all went to cable or cancellation, leaving us with more of the same ones that are dubiously popular over there (Beyblade? What the shell is that?!?!)
The problem is that now, more than ever the animation market is driven for profit, especially in tweenage teenybopper bubblegum sexist shows like Winx Club and Bratz (which basically is a recruitment series for future prostitutes of America!) The only Japanese shows they air outside of cable are all toy based (to be fair, Sonic X and Kirby were pretty fun).
Not to mention that because of 3 cable channels, networks fail to compete. ABC is just Disney's line up (and some of it is good, Lilo and Stitch, Emperor's new School, the Proud family), CBS is nick Jr crap (at the moment), and NBC is Discovery kids... like, who gives a rat's fez about Discovery kids.
The less said about Kid's WB the better, and 4Kids, which used to have some pretty good shows, has released a real discouraging fall line up... a cartoon about Pinatas.... who wants to watch that?
I've ranted about the death of syndication for a while now, due in part to trailer trash court shows, and Maury Povich's horrible "Who's the Baby's Daddy" talk show. It's pretty pathetic what shows they air, actually.
Though I feel a few shows (like the ones I mentioned prior) are well done, and there are great shows for adults like Family Guy, Simpsons, Aqua Teen Hunger Force, etc (not to mention a second series of Futurama to begin airing in 2008 on Comedy central), shows for kids don't have that same, Adult and child appeal they had just years ago. It's the toy conglomerates. And it's not even decent GI Joe or Transformers stuff, either.
