Only Murders in the Building (★★★★☆).The show ushers in several new notable guests, including Shirley MacLaine, Andrea Martin, Michael Rapaport, and Amy Schumer, playing a particularly daft version of herself. And, following a nearly flawless debut season, season two moves in a slightly meta direction, with its lead trio of sleuthing neighbors all acutely aware they’re trying to live up to the high expectations set by prior success.The series’ most successful component — the sparkling rapport between stars Steve Martin, Martin Short, and Selena Gomez as murder-solving, podcasters Charles, Oliver, and Mabel — remains gloriously intact.
