Only two shows have become classics on that channel: Dexter's Laboratory and Ed, Edd, and Eddy. These two shows are good, but other than that the others fall short. PS-If you want, you can add "The PowerPuff Girls" to the classics, but out of respectability I declined to do this.
People are clearly running out of ideas for shows, the old ones are way better and the guys who conceptualize these new shows think that better animation and CGI are going to compensate for the shows(usual) lameness. But I don't watch cartoon network as much as I used to so there might be some good new shown there I'm missing.
Cartoon Network is really cool because during the night Adult Swim is on and they have lots of good shows such as Robot Chicken! Who doesn't like that show! Or family guy or futurama who doesn't like those shows!
Cartoon Network is for little kids who ever watches it shouldent be on a computer, But after cn Adoult swim is on so that is the only good thing on the channel.
