This season, several returning series feel more like brand new shows, after undergoing significant casting and storyline overhauls to give their ratings a jolt. Kevin James’ CBS sitcom Kevin Can Wait added Leah Remini as a cast regular for Season 2, reuniting him with his King of Queens spouse—and killing off his new TV wife (Erinn Hayes) to make room. Season 7 of Once Upon a Time features a complete storyline reboot and the departure of six cast members, including stars Jennifer Morrison and Ginnifer Goodwin. And when NBC’s Taken—a prequel to the Liam Neeson films—returns in midseason for its second year, it will have jettisoned six regulars, with only Clive Standen (who plays the younger Neeson) and Jennifer Beals returning.
