By Craig Hubert | After demolishing the competition with its season three premiere, AMC’s zombie-drama “The Walking Dead” is oddly ready to change things up. The network renewed the wildly popular show for a fourth season but decided to part ways with its showrunner, Glen Mazzara over a “difference of opinion.” Mazzara took over for series creator and original showrunner Frank Darabont after he abruptly departed the series early in the second season. According to Deadline, there were “rumors that Mazzara was not happy on the show,” and, according to an unnamed source, “AMC is a tough place.” Considering their slate of successful shows – critically and commercially – that are soon ending, the network should start thinking about playing nice with the people who are keeping the network afloat. In the meantime, other showrunners have been taking to Twitter to air their frustrations over AMC’s mismanagement of their hit shows. Mazzara will stay on for the rest of season three, and no word yet on who will replace him. If Mazarra is looking for work, he can always jump over to his buddy Frank Darabont’s new show on TNT.
