Pilot season is in full swing, and one trend is emerging: Dad-driven family comedies are all the rage. Why? Broadcast networks seem anxious to replicate the success of Modern Family, ABC’s sophomore smash, which waltzed away with the Outstanding Comedy Series Emmy in August and is averaging an enviable 12 million viewers this season. NBC, CBS, and Fox all have shows in development for fall 2011 that have a Family feel: NBC is working on Man of the House, which is described as a Mr. Mom role-reversal show; CBS is shepherding an untitled sitcom from Peter Knight (Sweet Valley High) that focuses on the outspoken suburban father of a blended family; and Fox is turning the buzzy non-fiction book The Council of Dads into a half-hour comedy chronicling a group of six men who raise the daughters of a friend who died of cancer. After this year’s crop of lackluster shows, here’s hoping Father does know best.
