I guess this show has its defenders, but I think we can all agree it's unnecessary. I mean, Cleveland? He was basically just a prop in Family Guy. His only characteristic was being the voice of reason towards the group of Peter, Joe, and Quagmire. So why does Cleveland get a show? I guess it's something to have an animated sitcom with a primarily black cast, but does that actually make it entertaining???
The Cleveland show focuses on Cleveland and his new family. He moves to the backwater town of Stoolbend, Virginia, where he marries his old high school sweetheart Donna. She has 2 children, teenage teenager (for this is a character type to Seth MacFarlene) Roberta, and poorman's Stewie Rallo. Cleveland also has his somewhat bland son Cleveland Jr. who is now in his early teens, although on Family Guy he was younger.
Anyway, like most modern animated sitcoms such as The Simpsons, Family Guy, American Dad, and Futurama, the humor comes from the dysfunctional characters and the unlikely or unusual things that happen to them. In this case, the characters seem somewhat bland so most of the humor is situational. Occasionally the show is very funny, but most of the time each episode has only a few smiles, hardly worth half an hour. It should be noted that much of the humor comes from the supporting cast, like Tim the Bear and Lester, a redneck who is voiced by a black man, while Cleveland is voiced by a white man. Make of that what you will.
Anyway, were TV Tropes to have a rating system, I would give it 2/5, for being a money grab that the network won't stop buying more of because it's from MacFarlene. I mean a second season was ordered before the season 1 premiere! It is sometimes funny but I don't like most of the characters, and it's easily the weakest of Fox's animation lineup. I prefer The Simpsons and Family Guy to sitting through this show.
