When The Simpsons and Family Guy become repetitive, it's ok, because, well, they've earned it. They make continuity flubs, and that's ok too. American Dad hasn't earned that yet, so when they've got an episode devoted to Stan and his son Steve finding common ground a week after they had one, it doesn't sit well. When Stan references the pleasures of porn twice in one episode a week after they spent an episode singing the evils of it, that feels a little off too. American Dad has a lot of potential, but it is certainly not living up to much...
