1) “Masterpiece: Grantchester,” 9 p.m., PBS. This season has had mini-glimpses of the new vicar. Its first two mysteries were tackled by the original guy, the third by his assistant. Now, at last, Will Davenport (Tom Brittney, shown here) takes over. Riding a motorcycle and listening to rock, he gives this late-’50s, English village a jolt. He has no plans to help solve crimes … until a boy, silent and blood-stained, arrives. With one exception (the boy’s over-the-top father), the result is skillfully written and played. Read more…

1) “Heaven,” 8-10 p.m., Lifetime. Starting with “Flowers in the Attic,” Lifetime has soared big with movies based on V.C. Andrews novels. Now it will fill five straight Saturdays with her stories of the Casteel family. In this first one, Heaven Casteel (Annalise Basso, 18, shown here) is the oldest of five siblings in a mountain shack. A tragedy forces her into new worlds. Read more…

1) “Agents of SHIELD,” 8 p.m., ABC. A week from the season-finale (and a year from the series-finale), “SHIELD” has our attention. Tonight, ABC says, the team is in full crisis mode; that thrusts it toward next week’s two-hour finale, trying “to stop the end of everything,” a worthy goal. The series (shown here from its first year) had already been renewed for 13 episodes next summer, but ABC recently said that will be the end. Read more…

1) “iZombie,” 8 p.m., CW. Next week, two CW gems will depart. It will be the final episodes of “Jane the Virgin” on Wednesday and “iZombie” a week from today; add “Crazy Ex-Girlfriend” (which concluded this spring) and you have the network’s best shows. As for tonight … Liv – the doctor who accidentally became a crimesolving zombie – gets devastating news; also, Clive (shown here) does some society dancing. Read more…

1) “Jane the Virgin,” 9 p.m., CW. At the end of a terrific episode. Jane’s mom quietly asks: “How do we say goodbye?” Good question; after five seasons and 98 episodes, we hate to see “Jane” end. It started well (including a Golden Globe for Gina Rodriguez and a best-comedy-series nomination), stumbled a bit, but is ending with humor and warmth. This episode manages to settle most of the plot points, even providing some warmth for ex-spouses Rafael and Petra, shown here. In fact, one problem is disposed of quite spectacularly. We’re not sure what will be left for next week’s two-part finale. Read more…

1) “Modern Family,” 9 and 10 p.m., ABC, and more. In giddy stretches of the 1990s, a network would have 16-18 situation comedies. And next week? Counting everything (except cartoons), the broadcast networks will have a total of four sitcoms. Really. CBS and NBC had already replaced theirs with summertime reality; next Tuesday, most of ABC’s sitcoms will be replaced by the “Bachelorette” finale. So savor these laughs while you can,including “Modern Family” (shown here in a graduation episode), plus “The Connors” (8 p.m.), “American Housewife” (8:30) and “Black-ish” (9:30 and 10:30).
