Big shakeups are about to hit Dunder Mifflin. Paul Lieberstein will likely exit as showrunner next year, the better to focus on the Dwight-centric spinoff. Meanwhile, Mindy Kaling’s absence to work on her new series seems inevitable after the casting of Ed Helms, Bill Hader, and Richard Schiff in the pilot. So in theory, next year could see the loss of: the showrunner, an influential writer, Dwight, Andy, Toby, and Kelly. That’d make for an empty Scranton office, all right. I know this show is good at adapting, but isn’t it kind of time to close things out already?
