People who know me will know that I'm not a huge fan of Family Guy. It brings to mind a mashup of several different shows, all of which are better. It doesn't have the balls or the low production time to be as edgy and topical as South Park, it doesn't have the format or insight into culture to work the random haphazard cultural references of Robot Chicken or the technique and chops to be as funny as The Simpsons.
As for his other television shows, The Cleveland Show is, as far as I can tell, completely worthless (I've only watched a few episodes) and while American Dad always threatened to be, for the spy and action genres what Futurama is for sci-fi, it never had the writing or the intellect to cause that concept to work. (Side note: Another show in the same vein Archer is damn near one of the funniest things on TV right now, with fantastic parody shots at spy and action movies, and the Bond films in particular. You really should give it a shot).
Anywho, thanks to all this, you know when I say that And Then There Were Fewer is easily one of the best things to come out of Family Guy (if not THE best), you know I'm not screwing around. A fantastic note-perfect parody of a very specific type of movie (what kind would technically be a spoiler), which manages to be unique and clever without being full of itself. Bravo.
