To be fair though...
The fact Bob's Burgers even got to 3 seasons was amazing. The show didn't exactly have the best ratings, and it took years for the show to catch on. I should know, as I watched it from the beginning. I had the first Bob's Burgers T-shirt which was an unrelated logo that probably existed in the series' development. Went on clearance a couple weeks later. That could have very well been the only piece of merchandising the show got. The show was constantly in danger of being cancelled, and even when it became a massive cult hit, Fox wanted to sabotage it by giving it the King of the Hill/Futurama death slot so weaker sitcoms could flourish (which they didn't). Slowly but surely the show gained a cult following, and I wouldn't be surprised if that was all on adult swim rebroadcasts that were the reason. I mean, Bob's Burgers came out at a time when Fox was trying multiple other animated sitcoms. That awful Allen Gregory and the underrated and shoul have been on cable Napoleon Dynamite. Of which I'm disappointed didn't take, but if its sacrifice meant Bob's Burgers would get its chance, so be it.
So basically Bob's Burgers gets more buzz now than Family Guy and The Simpsons put together.
Meanwhile, The Cleveland Show had low ratings, mostly due to disinterest. While I contend that it was at least a superior show to Family Guy at the time with far more likable characters and even slightly better voice talent, I can see why a third Seth MacFarline Show ticked viewers off. Even though all Seth's involvement was voicing 2 characters and it was really Mike Henry's show.
