1) “Masterpiece: Grantchester” season-finale, 9 p.m., PBS. It’s been a terrific season, a quick rebound from the drab “Masterpiece: Endeavour.” Alongside some solid mysteries, there have been personal crises for Geordie (lost in an alcoholic funk) and Will (shown here, center, last season), who dallied with a temptress while overlooking Geordie’s good-hearted niece Bonnie. Last week, Geordie’s wife let him return home; now come more key moments, including another murder of a homeless man.
2) More finales. PBS follows “Grantchester” with another finale. That’s “Cobra Cyberwar,” with the prime minister and Anna fighting for their political lives, as the crisis peaks. Also, HBO wraps the “Westworld” season at 9 p.m. and the “Anarchists” documentary at 10.
3) “Power Book III: Raising Kanan” season-opener, 9 p.m., Starz. As the second season begins, Kanan is doubting his future in the drug world. Raq (played by Patina Miller, a Tony-winner in “Pippin”) tries to smooth family disputes while expanding her power.
4) “Celebrity Family Feud,” 8 p.m., ABC. The first half-hour has Kristin Chenoweth vs. Kathy Najimy; the second has the reality-show casts of “Summer House” and “My Unorthodox Life.” That’s followed (in a change from the usual order) by “$100,000 Pyramid” at 9 p.m. and “Generation Gap” at 10.
5) ALSO: Zachary Quinto discovers the story of his great-grandfather in “Who Do You Think You Are?” That’s 7 p.m. on NBC, followed by reruns of “Password” and “America’s Got Talent.”And an Elizabeth Taylor marathon on Turner Classic Movies includes two impressive (but overstuffed) epics – “Cleopatra” (1963) at 3:30 p.m. ET and “Giant” (1956) at 8. That’s followed at 11:30 by the blisterig, 1966 film, “Who’s Afraid of Virginia Woolf?”
