I honestly hope you weren't serious about Ren & Stimpy. What a load of BS.raxer92 said:-snip-
We defend our 'nostalgia' because we had fun. If we still enjoy a show as an adult that doesn't mean it's due to nostalgia, it means we still have fun watching it. Nostalgia does not keep someone from seeing the flaws in the work, since what we see as a kid and as an adult changes over time. That does not, by any means, mean a person can't still enjoy it.
The first cartoons were not made specifically for children, that has only become a recent trend. They had been mature and intended for adults.
Parents need to stop complaining when they see something violent that is drawn in a cartoon style, and not assume it is meant for kids, and to furthermore watch what their kids are looking at on TV in the first place (you know, show responsibility).
You should read up on the history of anime, what influenced it, and how it came about. You really don't seem to know as much as you think you do. More than half of them don't have coherent story lines, they have flying people and creatures with a lot of fighting, super powers, and swords. It was/is popular because it was different from American cartoons.
Americans do have their style, just because you refuse to see it for what it is doesn't mean they don't have it. They simply just don't draw everything exactly the same and have different styles for shows. It would seem you can't appreciate that.
Lastly, no show will EVER remain on the air until the end of time. People know that one day their show will end, what people are angry about are the choices that Cartoon Network has chosen to replace those shows with. Frankly, because almost all of them are garbage.
By the way, did it ever cross your mind that the creators of Avatar wanted to have a design similar to japanese anime because they actually liked the style, and didn't do it to intentionally compete with the market? It happens all the time, it's called influence.
