The network recently announced that showrunner Glen Mazzara will be stepping down from the series due to differences in opinion regarding the show's direction.
Deadline reports that Sutter, whose FX series is now in its fifth season, took to Twitter on Friday (December 21) to blast AMC for letting Mazzara go.
He tweeted: "AMC is run by small-minded, bottom-line thinkers who have no appreciation or gratitude for the effort of its creative personal (sic)."
Sutter criticised AMC for its "disrespect" to writers and viewers, adding: "Mazzara took the work-in-progress that was Walking Dead and turned it into a viable TV show with a future. Without him, that future is dim."
The Shield showrunner Shawn Ryan also damned AMC on the social networking site, adding: "AMC, WTF? Common knowledge that AMC cut Breaking Bad shorter than it should have been.
"Now you have creative differences w/ biggest hit's savior? With FX, Showtime, HBO, Starz, Cinemax, A&E, TNT and others to sell to, it's a real question now why good show runners should sell to AMC?"
The second half of season three of The Walking Dead returns in February 2013.
