Earlier today, we reported the surprising news that The Walking Dead showrunner Glen Mazzara has left the series. The move comes nearly a year and a half after he stepped in for series creator Frank Darabont. Just hours after the news broke, Sons of Anarchy creator Kurt Sutter and Last Resort creator Shawn Ryan blasted AMC on their Twitter pages. First up is the always-outspoken Kurt Sutter, who didn't mince words in his missive, calling certain AMC executives "cunts."

"AMC is run by small-minded, bottom-line thinkers who have no appreciation or gratitude for the effort of its creative personnel. Time and time again we see events like what happened today with Glen Mazzara. They continue to disrespect writers, shit on their audience and bury their network. Mazzara took the work-in-progress that was The Walking Dead and turned it into a viable TV show with a future. Without him, that future is dim. Showrunners are not development executives, we're not cookiecutter douchebags that you plug into a preexisting model. TWD will suffer. Even Zombies need consistency. Mad Men and Breaking Bad will be gone soon. So will AMC. I hope their fucking stock takes a dive and the shareholders line up (Josh) Sapan, (Charles) Dolan and (Charlie) Collier and shit in their open hands. Cunts."

Shawn Ryan, who also created the FX series The Shield which Kurt Sutter wrote and produced for, questioned whether writers should even consider pitching their material to AMC.

Today's announcement also revealed that AMC picked up The Walking Dead for a fourth season. However, it isn't clear who will be taking the reigns of this hit show next season.
