DFamily Guy is absolutely stunning!
At first glance it's just an adult version of the Simpsons- fat husband, hard working wife and two kids. But it is SO much more than that.
It's difficult to describe, but it is the best timed animation EVER. It's main contribution is its amazing use of flashbacks for comic effect.
But really, you have to weatch several of them to get the point. What often happens with Family Guy is that you are watching an eipiosde which is ok, amusing, but not really funny, and then suddenly they'll pull one huge joke that makes you miss the next five minutes, you are laughing so much.
They also have a very amusing baby with the brain of a criminal mastermind, though thw failure to be original with that plot has badly affected the second seris.
Well worth it, anyway.
