FlashForward showrunner Marc Guggenheim has departed the ABC series, reports AICN.

No reason has yet been cited for his exit, but worryingly, reports suggest that network executives have been unhappy with the quality of the show’s storytelling post-pilot.

The program, which stars Joseph Fiennes, Sonya Walger and Dominic Monaghan, was recently handed a full season order by ABC and has continued to do well in Thursday night ratings.

It is not yet known whether co-creator David Goyer will now serve as sole show-runner or if he will be joined by someone else.
