I usually make it a point not to watch Cartoon Network before 10 pm. Granted, the Adult Swim block is pretty dismal as well, but whatever. There are a few good cartoons still on CN, like Flapjack, Chowder and Ben 10, and even the Secret Saturdays, but the bulk of their programming is either crap from other networks (Johnny Test is on every time I turn my goddamn tv on) or some vapid imitation of Nickelodeon style nonsense. Shows like Total Drama Island and Stoked are just stupid and make little kids into jerks, and the few live action shows I've seen were pretty awful.
It seems like Cartoon Network has sold out pretty hard, if you ask me.
