The zombie drama scored an excellent 5.1 rating in the 18-49 demographic and 9.5 million total viewers Sunday. That was down from a 5.8 rating and 10.9 million last week, when it became the most-watched basic cable drama ever.
Last week's episode was also the most watched non-sports show on any network since the "American Idol" finale in May.
If its ratings continue to hold, the show has a legitimate chance to end the season as television's top-scripted show -- something no cable show has ever done.
Sunday's episode had 6.5 million viewers in the key demo,. Two episodes in, its average rating for 18-49 is better than that of any fall show except for NFL games.
