i really liked the first 3 seasons of Family Guy but the new ones IMO are terrible. They all rely on the same style of joke e.g. "Did you say golf?that reminds me of the time that i went on holiday with Margaret Thatcher" or something like that.
In the first few series there were still great irrelevant jokes but they weren't all structured the same way.
I think family guy has been ruined for me by an episode of South Park called cartoon wars. Check it out on
www.allsp.com and you will understand what i mean.
IMO South Park is by far the best cartoon.
