Not even that...
I just don't really enjoy the new direction they've been going in.
Cartoon Network was supposed to be the "Experimental" network. They took risks. It didn't always work (CN Real), but it gave us content that could not have been made on other channels.
Nowadays though, everything seems derivative of TTG or SU. It's like they're not even trying.
But again, I'm just a dumb asshole on a cartoon forum, so what do I know?
