At least it isn’t all preachy and up its own ass with messages.
South Park is brilliant, the Simpsons used to be. King of the Hill and Futurama were my personal faves.
Family Guy is so hit or miss, sometimes they're spot on -- other times, they're just offensive, and pointlessly so.
They push boundaries, but there's nothing behind it plot-wise -- its just offensiveness for offensiveness' sake.
