I think the show is only worth continuing if Mitch Hurwitz was at the helm running it. I think he's the genius behind it. And he hasn't yet come to that decision to continue the show.
Every so often, it's time to make a change with a showrunner. You evaluate the creative and how the show is run and how the writing staff works, and sometimes you want to freshen the show. We just decided that it was time to do that on Community, and no disrespect to anyone.
