The Walking Dead is a television adaptation of a popular comic series. It follows the typical post-apocolyptic set up as most zombie shows, but has been outstanding thus far. They really deliver on the overwhelming feeling of massive Romero type zombie hoardes and do a great job of depicting the man vs. man emotional element. On top of that the make up and puppets look outstanding.
This is a series that you won't want to miss. The first season has already come and passed, but a second season debuts on Halloween of this year.
