I know a lot of people hate the way Cartoon Network ended up, but I think it's almost on par with itself from 1998-2004. I love shows like Adventure Time, Regular Show and Flapjack.
I didn't like Cartoon Network very much for a long time. Foster's was the only show I got into, but that wasn't enough to keep me interested in the network.
As a side note: I really miss Two Stupid Dogs.
