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. Read more…

1) “Bonnie and Clyde” (1967), 8 p.m. ET, Turner Classic Movies. In real life, Clyde Barrow was an ex-con who met Bonnie Parker, a 19-year-old waitress with an estranged husband. They launched a three-year crime spree; despite murders (including nine lawmen), their five-person gang became Depression celebrities. That’s captured brilliantly in this film, which drew 10 Oscar nominations, including its stars (Warren Beatty and Faye Dunaway, shown here) and best picture. Read more…

1) “Magnum P.I.,” 9 p.m., CBS. Fans of this show are in a better mood now: CBS didn’t renew it for next season, but NBC has stepped in with a partial reprieve – 10 episodes in each of the next two seasons. For now, CBS has “Magnum” reruns; tonight, one private eye is tracking another: Magnum is suspicious of Higgins (they’re shown here in a jollier episode); he’s unaware that she’s undercover in a group that’s trying to destroy the MI-6, the British spy service.

1) “Generation Gap” debut, 9 p.m., ABC. There’s an all-star squad in the background of this one. Mark Burnett, the “Survivor” chief, is one of the producers; others include talk-show hosts Kelly Ripa and Jimmy Kimmel. Ripa (shown here) is the host, with a basic task: She asks kids and their grandparents questions about their respective eras Read more…

1) “The Challenge: USA” debut, 9:30- 11 p.m., CBS. Here’s CBS’ key newcomer for the summer. It takes 28 previous contestants from four reality shows, giving them super-sized physical challenges. (Shown here, Lee Temory and Tiffany Mitchell descend from a skyscraper.) Some of these people are already winners; that includes three “Survivor” champions (Tyson Apostol, Ben Driebergen and Sarah Lacina) and one apiece from “Amazing Race” (James Wallington), “Love Island” (Justine Ndiba) and “Big Brother” (Xavier Prather).

1) “America Outdoor” opener, 9 p.m., PBS. Something about Death Valley doesn’t seem inviting. Maybe it’s the name … or temperatures that can reach 134 degrees. But two million people visit each year, Baratunde Thurston (shown here) says, and a few stay. A former mining town of 4,000 now has a population of one. That guy arrived from Austin, Texas, four years ago with friends and stayed alone. He’s turning the general store into a museum; he also survived a snowstorm – really – that stranded him indoors for 4-5 days. It’s an appealing start to the series Read more…
