1) “Masterpiece: Grantchester” season-opener, 9 p.m., PBS. After the disappointing little “Endeavour” season, “Masterpiece” bounces back strongly. There are six solid mystery hours, each against the backdrop of personal stories. Will, the crime-solving vicar, continues to make a mess of his romantic life ,,, his former curate runs a coffeeshop … and his housekeeper has a crisis. (They’re shown here.) Also, his police pal Geordie has been badgered by his boss and ousted by his wife. The boss part is overwrought, but the rest provides nuanced layers to smart mysteries..
2) “Final Straw” debut, 9 p.m., ABC. After waiting for the basketball and hockey playoffs to end, ABC makes its summer game-show push. On Thursday, it returned “Press Your Luck” and debuted “Generation Gap.” Tonight, it launches this show, with contestants trying to pull things – basketballs, kitchen appliances, etc. — from a Jenga-style tower. Janelle James, the “Abbott Elementary” principal — hosts. She’s sandwiched by the season-openers of Steve Harvey’s “Celebrity Family Feud” at 8 p.m. and Michael Strahan’s “$100,000 Pyramid” at 10.
3) “Who Do You Think You Are?” season-opener, 7 p.m., NBC. It’s been a circuitous journey for this quietly likable show – three seasons on NBC, seven on TLC, almost three with no home. Now it returns to NBC; this is like PBS’ “Finding Your Roots,” except it makes celebrities travel around to see what experts have found about their ancestors. That starts with an interesting hour with Billy Porter; others will include Allison Janney, Nick Offerman and more.
4) “Patagonia: Life on the Edge of the World” debut, 9 p.m. ET, CNN, rerunning at midnight. Sprawling across almost 1,000 miles of Chile and Argentina, Patagonia offers ideal turf for nature filmmakers. Now CNN uses modern technology for this six-part series. It’s narrated by Pedro Pascal (“The Mandalorean”), a Chile native who has back-packed in Patagonia.
5) ALSO: “Big Brother” takes its Sunday slot at 8 p.m., sliding “Equalizer” and “NCIS: Los Angeles” to 9 and 10. The show is also at 8 p.m. Wednesdays and 9 p.m. Thursdays. And PBS surrounds “Granchester” with other strong international dramas. At 8 p.m., “Hotel Portofino” sees Danioni, the corrupt local politician, cause trouble for Lucian and for his parents’ marriage; at 10, “Cobra” sees a British strike force, organized to respond to emergencies.
