AMC Picks a New Showrunner on The Walking Dead, but how long will this one last?

There's a new sheriff on AMC's The Walking Dead. Scott Gimple has stepped up to lead the cast of survivors into their fourth season. Last month Glen Mazzara stepped down from his perch as showrunner on Walking Dead, amidst a swirl of rumors that Mazzara and comic book creator Robert Kirkman did not hit it off.

According to TV Line, Glen Mazzara will finish out the third season, and Gimple will step in and take over on the fourth. Let's hope they can keep it together — the show just started getting good again this year.
