This is a very funny, entertaining show. It is unlike family guy in that the jokes in this aren't random, they don't cut away to a past experience of something stupid like family guy. Watch out for roger the alien or klaus the goldfish, they are the two best characters of the show

I'm soooooo sick of people talking about family guy when american dad gets mentioned. They both have their place, if you have a low attention span and have a simple sort of humour then family guy is for you. If you like plot and character development and something a little more intelligent that doesn't have to cut away every few seconds like the time I got caught in a blender *cut to pointless blender scene* then go for american dad. I have every box set they have out so far and it's odd as they mix up the series episodes and miss out ones completey but they turn up in another box set. Odd way of doing it but as long as I get all of them I'm not fussed. Stop comparing the two and just enjoy each of them for their individual merits. The first series is the best for me though - current, intelligent and very individual.

American dad is waaaaaaaaaaay funnier than family guy, more grown up and less sketchy (family guy always cut away to some degrading/george bush/taliban type sketch to draw a few laughs)
Honestly american dad tops the bill!!
