The Walking Dead tells the story of the aftermath of a zombie apocalypse and follows a small group of survivors traveling across the United States in search of a new home away from the hordes of zombies. The group is led by Rick Grimes, who was a police officer in the old world. As their situation grows more and more grim, the group's desperation to survive pushes them to do almost anything to stay alive.

The Walking Dead premieres on AMC on October 31, 2010.
Based on the comic book series, this show is about zombies. The first season will be 6 episodes long, but AMC might pick up another longer season two if it does well it the ratings. Looks very interesting.

So I've been trying to avoid The Walking Dead all this time simply because I was so disappointed that I wouldn't be able to see it. But now...I can't wait till 10pm! This actually made what I thought was gonna' be a crappy Halloween (no plans for a multitude of reasons) into a good one!
