When I think of Family Guy, I think of how awesome it was that a show that was canceled was so popular that it was brought back by sheer demand, illustrating the power of fans.
Then I see what has happened and think "boy, we kinda screwed up here." Because once the show returned it's like they had carte blanche to do whatever they want with total disregard for simple concepts like theme and cohesion. The show is like a running fart joke told by your drunk frat boy friend over an excrutiatingly long period of time while all you want to do is go back to trying to talk to the girl across the table into going back to your apartment to help you practice repopulating the Earth after the Zomb-pocalypse. Worse, the show has suddenly become a 30 minute soap-box for far-left idealism and an extreme secular progressive agenda, which doesn't necessarily bother me except for the fact that more and more often they seem to get so caught up in spouting off a political opinion that they FORGET the PUNCHLINE. For all the hate Cleveland has been getting for his show, on his final appearance on the Family Guy show he aced everyone by pointing out how the characters have little to no depth, character development has all but been reduced to nothing, they've dropped any pretense of having an episode-long storyline, and tired old Chicken fight jokes.
For me, I stopped watching once my two favorite characters went tits up... Stewie and Brian.
Brian in the first seasons was the "realistic" character, the sort of straight man that grounded the show somewhat in the realm of realism despite the absurdity that he was a "talking dog". For example, the episode where he bit someone and was going to be put to death and decided to study and lead his own defense, and upon his opening statement the judge says "Why the hell are we listening to a damn dog?" completely wrecking his moment of glory. His sobering persona was a perfect balance to Peter's insanity and with the non-sequitor humor managed to find it's place in the irreverent humor the show capitalized on in it's first few seasons. Now Brian walks around with an overbearing "holier than thou" elitist yuppy attitude, instead of drowning his sorrows in a martini as a method of coping with the absurdity of the situations going on around him.
Then there is stewie who has gone from being ICONIC to being a completely throw away character. The comparison is startling and evident immediately... he has gone from "You will RUE the DAY!" to "Ooooh I can't wear white after labor day!" It was funnier when there was an aire of uncertainty as to his sexual proclivity but now that he's just plain out of the closet he loses his relevance. The evil genius thing worked and was funny because the character sold it so well... It's hard to imagine the current stewie plotting and destroying his own delivering doctor in a creepy yet satisfying homage to Child's play. Now he's throwing Bennie Hill Parties and lacks any of the punch he once had... Stewie was the character who was at once charmingly witty and yet frightening in his ability to become a little serial killer in training.
Worse, Can you think of any story involving Meg or CHris lately? It's almost as if they've been written out of the series... Chris has been relegated to a walk on role, and Meg when she appears has fallen so much victim to the "everyone hates Meg" running gag that she doesnt even have speaking roles anymore. Which is sad, because in a way Meg was a very real character that evoked a level of empathy and added a dimension to the show that has since been lost.
I won't be surprised if Family Guy ends up canceled in another season or two. I don't see it lasting as long as the Simpsons, although to be fair, the simpsons stopped being funny and/or amusing to me somewhere around Season 4, and I havent watched it since. American Dad is just too low-brow and stupid for me to really enjoy, but surprisingly I enjoy the Cleveland Show alot. I think the reason is because the Cleveland show concentrates ON it's characters and while some people don't like it now, I attribute that to the show trying to establish the characters. It certainly has more structure than Family Guy, with a decided plot and a sitcom style. A few of the random jokes from Family GUy have bled over, but i think thats to help acclimate people to the show... the last episode where Cleveland gets a job (again, establishing the character) was pretty funny, and Ariana Huffington as Mrs. Bear is a gem. Time will tell if the show pans out but I equate it to King of the Hill.. the first season started off a bit slow but eventually it hit it's stride and became a great show, probably the best Fox had in it's animated line-up.
Given the results of Family Guy's return, I think I may hold off on signing anymore "Bring back Buffy/Firefly" petitions. I'm just too afraid of what those two shows might become if they are resurrected simply as a vehicle for ratings and increased advertising revenue for the network.
