I gave up on Family Guy about a year after it was uncancelled. You can only do the whole "Republicans are evil!" stick for so long before it becomes tired and now it's just annoying. The only good things left are the Star Wars parodies as they come and even them are littered with horrible jokes
American Dad, Cleveland Show, Bob's Burgers: gave them all a chance and left after an episode or two. Come to think of it, only thing I watch on FOX now is NASCAR.
