1) “Homeland” series-finale and “PennyDreadful” debut, 9 and 10:10 p.m., Showtime. One of the all-time great series concludes. Carrie (the superb Claire Danes) returns to Afghanistan, trying to revive the peace treaty. That’s followed by a stylishly filmed tale set in 1938 Los Angeles, complete with Nazis, old Hollywood, radio evangelism and the demons of Mexican folklore. That last part is an odd but interesting detour from a strong drama, with the terrific casting of Nathan Lane as a crusty cop.
2) “God Friended Me” series-finale, 8 and 9 p.m. CBS. In a landscape stuffed with cops, courts and doctors, this show has crafted human-drama tales. Each week, Miles gets a request from a mysterious “God account.” Ratings started strong and slipped 20 per cent the second year; fortunately, CBS gave producers time to fashion this finale. In the first hour, Miles works with the son of the creator of the account’s algorithm. In the second, the account sends Miles to his sister, on the eve of cancer surgery.
3) “Zoey’s Extraordinary Playlist,” 9 p.m., NBC. This show’s catchy notion – Zoey hears people’s inner thoughts via pop songs – has had its ups and downs. Tonight, however, several songs work perfectly. One group number is in a funeral home, another at work. Bernadette Peters has a cemetery solo and there’s a funny duet in a karaoke bar. At these moments, “Zoey” is a delight.
4) “NCIS: Los Angels,” 10 p.m., CBS. Here’s a dead-serious episode, mirroring the real-life case of Eddie Gallagher, the SEAL whose demotion was overruled by President Trump: A SEAL leader is accused of severe misconduct; Sam (an ex-SEAL), Callen and newcomer Rountree head to Afghanistan … and a lethal crisis. Catherine Bell appears briefly, as her “JAG” character, now a lieutenant colonel.
5) Also: “American Idol” (8-10 p.m., ABC) starts its social-distancing phase, with performers at home. “Batwoman” (8 p.m., CW), has a high-octane hour in which Kate has a crisis of conscience; it’s very well-made … and very violent. “Masterpiece: World on Fire” (9 p.m., PBS) has another terrific hour, with Harry in wartime France and Kasia in the Polish resistance. And “America Together” (10 p.m. ET, Fox News Channel) shows people offering faith and perseverance during the era of the virus.
