AMC has just announced that they have renewed their flagship horror-drama The Walking Dead for a fourth season, but the good news has been tempered by bad, as they have also announced that Glen Mazzara, who served as the showrunner after the abrupt departure of original showrunner Frank Darabont during the second season, is leaving.
Many fans are not surprised with Mazzara’s departure, despite his run on The Walking Dead being a massive ratings success, due to AMC’s recent string of problems with showrunners with their other shows, and the fact that The Walking Dead did not have an early pickup.
“Both parties acknowledge that there is a difference of opinion about where the show should go moving forward, and conclude that it is best to part ways,” AMC and Mazzara said in a joint statement. “This decision is amicable and Glen will remain on for post-production on season 3B as showrunner and executive producer… AMC is grateful for his hard work. We are both proud of our shared success.”
