1) “The Son” series-finale, 9 p.m., AMC, rerunning at 10:05. A two-season run ends with fierce jolts. At the core are three generations (shown here). Eli attacked the Garcias and stole their land; Pete rescue Rose Garcia (whom he loves) and is ready to testify against his dad in court. But last week, his daughter Jeanne told the plan to Eli. Now we see the aftershocks. We also flash back to Eli’s youth, as he leaves the Comanche — and forward to Jeanne as the ranch’s elderly owner.
2) “Saturday Nighr Live,” 11:29 p.m., NBC. For the second straight week, this reruns an episode hosted by a Marvel co-star. Last week was Paul Rudd; this time is Don Cheadle, who was Lt. Col. Rhodes in the “Iron Man” and “Avengers” films. Gary Clark Jr. is the music guest.
3) “Magnum, P.I.,” 8 p.m., CBS. In a rerun, Magnum has double trouble: He’s kidnapped and he learns that his ex-girlfriend (Jordana Brewster) is in Hawaii, wih plans to steal a fortune. He still holds a grudge, because she’s the reason he and friends spent years as prisoners of war.
4) “Beauty and the Beast” (1991), 6:55 p.m., Freeform. This gem – an Oscar-nominee for best picure – is the center of an animation trio. “Monsters, Inc.” (2001) is at 4:50 p.m., with “Zootopia” (2016) at 9.
5) “Daughters of the Dust” (1991) and “The Learning Tree” (1969), 8 and 10 p.m., Turner Classic Movies. Both were selected for the National Film Registry; both reflect eras when black filmmakers had few opportunities. “Dust” is Julie Dash’s look at the island life of South Carolina’s Gullah people; “Tree” was from master photographer Gordon Parks, adapting his novel about 1920s Kansas boyhood.
