SEASON PREMIERE: Last season, the only reason to watch this sitcom about a TV news operation was the presence and performance of Andrea Martin, playing the mother of Briga Heelan’s Katie. Katie works as a producer at a cable news station, and Martin's Carol signed on as an intern. This season, Katie has grief from above as well as below. She has a new boss, played by this series' executive producer, Tina Fey.
