What’s on TV Saturday: ‘Won’t You Be My Neighbor?’ and ‘One Day at a Time’

“Let’s make the most of this beautiful day”: A touching documentary on Mister Rogers airs on HBO and PBS. And the third season of “One Day at a Time” lands on Netflix.

What’s on TV

WON’T YOU BE MY NEIGHBOR? (2018) eight p.m. on HBO and PBS (examine native listings); stream on HBO platforms. Grab these tissues! This portrait of Fred Rogers by the documentarian Morgan Neville (“20 Feet From Stardom”) reveals a man who genuinely sought to attach with kids. With the assistance of associates, puppets and visitor stars, the host used his quirky TV program “Mister Rogers’ Neighborhood” to coach kids on weighty points like demise, divorce and racism. Neville digs up tear-jerking moments from the present, and reintroduces the person behind Mister Rogers, one who thought kids’s applications had been too violent or condescending and who persevered regardless of criticism from politicians and skeptics. In addition to this HBO debut, the film will broadcast on PBS’s “Independent Lens” in honor of Mister Rogers’s dedication to public programming.

SATURDAY NIGHT LIVE 11:30 p.m. on NBC. Quite a few celebrities — together with Stevie Wonder, Jennifer Lopez and Lady Gaga — have carried out it. Now it’s Halsey’s flip. The pop star is serving double-duty as host and musical visitor on “S.N.L.,” months after the discharge of her ubiquitous single, “Without Me.”

What’s Streaming

ONE DAY AT A TIME stream on Netflix. This heartwarming multicamera sitcom, a modern take on Norman Lear’s 1970s classic, returns for Season 3. This time around, Penelope (Justina Machado), a single mother, faces tough conversations with her children about sex and drugs and falls for an overprotective father. The format is more traditional than most modern comedy series, and the show — with Rita Moreno as the matriarch — still delivers laughs. In her review for The New York Times, Margaret Lyons called the sitcom “energetically political and progressive,” one that “radiates delight.”

DANIIL TRIFONOV stream live at 8 p.m. on medici.tv. The Grammy Award-winning Russian pianist Daniil Trifonov — who is yet to turn 30 — performs works by Beethoven, Schumann and Prokofiev at Carnegie Hall, as part of the venue’s Keyboard Virtuosos II series. The Times’s chief classical music critic, Anthony Tommasini, said Trifonov was one of the best surprises in the genre in 2018 and called him “a brilliant virtuoso with poetic sensibilities.”

DON’T WORRY, HE WON’T GET FAR ON FOOT (2018) stream on Amazon; rent on Amazon, Google Play, Vudu or YouTube. Joaquin Phoenix portrays the irreverent cartoonist John Callahan, who died in 2010, in this biographical drama by Gus Van Sant. The movie picks up when Callahan, an alcoholic, gets into a catastrophic accident that leaves him quadriplegic. He decides it’s time for a change and joins Alcoholics Anonymous, where he meets his charming sponsor (Jonah Hill) and discovers a knack for drawing edgy newspaper cartoons.
