The zombie craze continues. I think we can safely say that The Walking Dead‘s first season finale next week will do gangbuster ratings. The penultimate fifth episode of the AMC zombie drama last night drew 5.6 million viewers, a series high, besting the series’ monster premiere that averaged 5.3 million. In adults 18-49, the series, which has already been renewed for Season 2, attracted 3.7 million viewers, also a record.
