What do you mean King of the Hill got canned to make room for the Cleveland Show? If that is true, I can only hate that Cleveland Show even more. The Cleveland Show is criminally bad.
As for the Simpsons, I am pretty Ho-hum about it, live or die, I don't care. The Simpsons had hit multi-seasons spanning lows when it stop being about the Simpsons and completely focused on Homer. Endless seasons of Homer, unending episodes of that fat **** and his next adventure into idiocracy. The same thing happened to Family guy, just endless fucking Peter episodes. The Simpsons had HUNDREDS of characters more interesting than Homer and they were telling me there was nothing else interesting to tell me about them over 23 fucking seasons? Yet everytime, it's Homer does stupid, problems arise from stupid, crisis resolves itself when everyone else picks up Homers slack and Homer gets hit with blunt objects enough times per episode.
If it dies, I can only hope they get some fresh meat, not more Seth McFarlane. I like 2 out of his 3 shows with American Dad easily the most consistently funny.
Bring back The Tick, anything, something different that isn't another animated nuclear family sitcom.
