Chris Mundy has been ousted as showrunner of the 'Criminal Minds' spinoff, leaving Ed Bernero to pull double duty on as head of both 'Minds' dramas.

Mundy served as a writer and co-executive producer on the original 'Criminal Minds' before being handed the reins of the spinoff. However, according to Deadline Hollywood, CBS was unhappy with the show's creative direction and brought in Bernero.

The spinoff, titled 'Criminal Minds: Suspect Behavior' and starring Forest Whitaker and Janeane Garofalo, will begin a 13-episode run at midseason.

Having one showrunner for a mothership show and its spinoff isn't out of the ordinary at CBS. Shane Brennan runs both 'NCIS' and 'NCIS: LA.'

Besides his work on 'Criminal Minds,' Mundy has worked on 'Cold Case' and 'Chicago Hope' among other programs. According to Variety, he had never served as a showrunner before.

With Bernero running both shows, executive producers Simon Mirren and Erica Messer will have more control at 'Criminal Minds,' but Bernero will still be the showrunner.

This shakeup mirrors another that happened at CBS with 'Blue Bloods.' In August, executive producer Ken Sanzel exited the show due to creative differences with star Tom Selleck. The change had little to no effect, seeing as 'Blue Bloods' is a ratings winner this season.
