1) “Grantchester,” 9 p.m., PBS. We’re down to the season’s final two episodes, with mysteries to solve – including a good one tonight – and personal crises to face. Geordie, the cop, descended into alcohol and gloom; his wife ousted him and brought in her good-hearted niece, Bonnie. Will the vicar (shown here, center, in a previous season) likes Bonnie, but dallies with a temptress who is engaged to Geordie’s boss. Some of that will be confronted now, with the rest next Sunday.
2) “Becoming Elizabeth” season finale (Starz) or “In Their Own Words” (PBS), both 8 p.m. TV’s fascination with the British crown seems endless. Starz goes back to the first Elizabeth’s struggle to be queen; you can catch the full season starting at 1:08 p.m., with the finale rerunning at 9 and 11:01 p.m. Jumping ahead almost 450 years, PBS has the story of Princess Diana … who is also the subject of a new HBO documentary next Saturday.
3) “Westworld,” 9 p.m., HBO. It’s the season’s second-to-last episode of this acclaimed show. In its first three seasons, “Westworld” won seven Emmys and was up for 45 more. (This fourth season – which began more than two years after the previous one ended – won’t be eligible until next year.) This high-tech epic is preceded at 7:12 p.m. by its opposite – “Belfast” (2021), the masterful boyhood memoir that Kenneth Branagh filmed in black-and-white.
4) “City on a Hill,” 10 p.m., Showtime. Two great actors are entangled in tough stories. Aldis Hodge is DeCourcy Ward, an idealistic prosecutor in early-’90s Boston; his dad (Ernie Hudson) refuses treatment while dying of cancer. Kevin Bacon is Jackie Rohr, a former FBI agent, unaware of the extremes of his new employer (Corbin Bernsen), who date-raped a daughter’s friend, then visited her later. Tonight tests the depth of Jackie’s corruption.
5) ALSO: Lifetime continues its lustful theme: In “The Art of Passion,” at 8 p.m., an emergency-room doctor finds her work entangled with an erotic love life; at 10 is a rerun of Saturday’s “A Dangerous Affair,” with a Pilates instructor’s erotic love life. For less eroticism (and more dancing), a Gene Kelly marathon on Turner Classic Movies peaks with the acclaimed “On the Town” (1949) at 8 p.m. ET and “An American in Paris” (1951) at 10.
