TV picks: 'Instinct,' 'Station 19,' 'Krypton' and more

Saturday Night Live. Bill Hader, whose new HBO comedy, Barry, premieres March 25, returns to  his old show  for a second time as host, and we can only hope he's bringing Stefon with him. Arcade Fire is musical guest. 11:29 p.m. Saturday, NBC.

Instinct. If I've learned anything from television, it's that law enforcement can't do its job without the help of outside consultants — magicians, mentalists, mystery writers — who don't have to play by the rules. Alan Cumming (The Good Wife) brings a slightly different set of skills to the NYPD  as Dr. Dylan  Reinhart, a CIA operative-turned-professor who finds himself assisting Detective Lizzie Needham (Bojana Novakovic) when a killer appears to be using Reinhart's best-selling book as a how-to guide. The setup isn't groundbreaking, but Cumming's character, who has a husband, Andy (Daniel Ings), who'd rather he stuck to academia, is, if only for the matter-of-factness of that one biographical detail. 8 p.m. Sunday, CBS.

Family Guy. Sir Ian McKellen guest-stars as a child psychologist  in an episode meant for those who can't get enough of  Stewie, who does most of the talking (and whose accent McKellen's character fails to acknowledge). 9 p.m. Sunday, Fox.

The Chi. Lena Waithe's Chicago-set coming-of-age drama, already renewed for a second season, ends its first. 10 p.m. Sunday, Showtime.

Arthur Miller: Writer. Filmmaker Rebecca Miller's portrait of her late father — who was, as she notes, a giant of the American theater long before her birth — benefits from his willingness to let her film and interview him. Her affection for her subject comes through, but in investigating his personal life, she appears to have flinched only once, putting off till too late an interview about her brother Daniel, who has Down syndrome and who grew up in an institution, publicly unacknowledged by his father. 8 p.m. Monday, HBO.

Krypton. Prequel from David S. Goyer (Batman Begins, Batman vs. Superman) stars Cameron Cuffe as the future grandfather of Superman, who, while living under an oppressive regime, is confronted by the kind of  dilemma only time travel can produce: Should he save his home planet (which looks, honestly, like a depressing place) or let it be destroyed so his descendant can become a hero somewhere else? (If he chooses wrong, do I lose my childhood comics collection all over again?)  10 p.m. Wednesday, Syfy.

Station 19. Grey's Anatomy spinoff launches with two-hour premiere. Jaina Lee Ortiz stars as firefighter Andy Herrera, whose father (Miguel Sandoval) also happens to be her captain. Her romantic life is also complicated — did I mention this is a Grey's Anatomy spinoff? — which leaves only a little head space for our thinking about Ben Warren (Jason George), the Grey's surgeon who recently decided he'd rather be a firefighter, but whose tendency to talk about surgery at meals isn't winning him friends at the station. It's all kind of convoluted, but convoluted is what Shondaland does best, so  I wouldn't bet against it. 9 p.m. Thursday, ABC.

Hope & Fury: MLK, the Movement and the Media. As the 50th anniversary of the Rev. Dr. Martin Luther King Jr.'s assassination approaches on April  4, this documentary, produced by NBC News chairman Andrew Lack and narrated by anchor Lester Holt, looks at the intersection of the civil rights movement and media. Includes some images never before seen on NBC. Hank Klibanoff, coauthor with former Inquirer executive editor Gene Robert of  the Pulitzer Prize-winning The Race Beat, and himself a former Inquirer reporter and editor, is among those interviewed. 8 p.m. March 24, NBC.
