@Jeepers: This thread is from March 16th. I'm not sure why you felt compelled to bump it, but your opinion would be better discussed in a thread outside of this one. So if it's going to continue let's stay on topic, please.
@ThePRPD: I feel the same way about The Cleveland Show, but as M.D explained they are animated by different companies which does make a difference in the animation quality. I think The Cleveland Show and American Dad both have better quality animation than Family Guy.
Overall, I feel like there's more effort put into "The Cleveland Show" in general. I think the writing quality is better, and there's more consistent characterization too. Family Guy is too hard for me to watch sometimes because Peter Griffin's character is too inconsistent so it's nigh-impossible to identify with or relate to him. (What's worse, he's the title character.)
But Cleveland seems like someone you might meet or know in real life, and he's one of the main reasons why I like the show so much.
I thought he'd only work as a sidekick type and never imagined he'd be able to carry the show as the lead character. I'm glad I was proven wrong.
