DON'T MISS: "The Good Wife" -- It may not garner the buzz and ratings of other top-flight dramas, but in its fifth season, this legal thriller continues to be one of prime time's best. Now comes a game-changing episode called "Hitting the Fan," in which Alicia's (Julianna Margulies) secret plot to start a new firm with Cary (Matt Czuchry) is finally exposed. That triggers an intense, gripping hour as emotions boil over, battle lines are drawn and a desperate struggle to retain clients begins. 9 p.m. Sunday, CBS.
