Cartoon Network is no Disney Channel. It’s really off the wall and bizarre at times. It’s geared toward older elementary kids, esp. boys who are tickled by irreverent humor, although college kids seem to be fans, too. It’s fairly harmless, silly fun. And, yes, the plots are incoherent, but so are most adult shows/movies nowadays. I’m convinced most of today’s media entertainment is written by potted-up, Peter Pan, pajama clad adults, anyway.
Of all the things to get worked up about, I would put this really low on the list.
