Personally, I am not a big fan of the current US TV animation style. It just seems sloppy to me. While during the time period that anime on afterschool and Saturday morning television blocks, I was not following the TV animation scene as much, I do remember some series from the time like Rugrats and Ren and Stimpy that had good animation quality. We also had series like Beavis and Butthead that weren't as high quality as some of the other animation offerings, but that series was more of a vehicle to show music videos in a humorous way. And of course, some series in the US had animation that was outsourced to Japan (some of the Teenage Mutant Ninja Turtles episodes had animation done by Toei if I remember correctly).
its especially annoying when they take the mature content out and put 'this is for older viewers' warning before the show starts.
I guess I understand why works get censored when the localized release is targeted toward children, but when censorship changes the meaning or tone of a work, it has gone too far. There is no excuse for that, and it is an insult to those who created the original work as well as the fans. It would be like painting clothes onto the "Birth of Venus" so that it could be presented in an educational situation. To me, such censorship is offensive, even obscene, and it is something that I will never support.
