Week’s top-10 for Aug. 12: Post-Olympics, summer shows return

1) “America’s Got Talent” return, 8-10 p.m. Tuesday, NBC. After eight weeks of auditions and a two-week Olympic break, the summertime ratings leader (shown here) finally reaches its live episodes, with viewers voting. That will be on five Tuesdays (with a results hour at 8 p.m. Wednesdays), pointing to the Sept. 17-18 finals.

2) “American Ninja Warrior” and more. Sidelined by the Olympics for 17 days, the NBC line-up is back. That’s led by new rounds of “Ninja” (8-10 p.m. Monday) and “AGT,” plus reruns of “Chicago” shows (9-11 p.m. Wednesday), “Law & Order” shows (8-11 p.m. Thursday) and “Saturday Night Live” (11:29 p.m. Saturday).

3) “MasterChef” return, 8 and 9 p.m. Wednesday, Fox. After a three-week break, the show doubles up on episodes. In this week’s first hour, people make birthday cakes; in the second, they work as teams, with ingredients specific to each generation.“Gen X” has lost two chefs and “Millennials” lost one; others are intact.

4) “OceanXplorers” debut, 9 p.m. Sunday, National Geographic. After conquering movies (“Titanic,” “Avatar”), James Cameron tackles deep-sea non-fiction. He’s filled a ship with scientists and tech, plus two mini-subs and a helicopter. Over six Sundays, they’ll follow whales, sharks and more to previously unseen spots.

5) “NCIS: Sydney” return, 9 p.m. today, CBS, When a U.S. sailor dies of radiation in Australia, a task force is formed. Olivia Swann plays a by-the-books NCIS agent; J.D. Lasance plays a free-form Aussie cop. They’re opposites (albeit attractive ones) turned allies. Now the eight-episode season, an entertaining one, starts its reruns.

6) “Bad Monkey” debut, Wednesday, Apple TV+. There’s a sort of “Florida Noir” genre, putting bright, sunny settings alongside weird people and ‘gators. That’s ranged from Netflix’s “Florida Man” to novels by Elmore Leonard, Dave Barry and Carl Hiaason – whose book became this 10-part romp with Vince Vaughn.

7) More streamers. As the Olympics end, streamers leap in. “Jackpot” (Thursday, Amazon Prime) has Awkwafina winning billions and hiring John Cena to protect her. Netflix has five “Emily in Paris” episodes Thursday and “The Union” on Friday, with Halle Berry and Mark Wahlberg as long-ago sweethearts, in a spy adventure.

8) “Young Sheldon,” 9 p.m. Thursday, CBS. The final season, with brilliant moments, is being rerun. In this episode (four weeks from the finish), Sheldon’s grandmother has a tough probation officer (Oscar-winner Octavia Spencer); also, Georgie gets some marital advice from his new father-in-law.

9) “Mammals,” 8-9:20 p.m. Saturday, BBC America. A brilliant series concludes (except for a making-of episode next week) with a visit to forests. We see chimps molding tools … Siberian squirrels gliding in the sky … and the first film of a bobcat catching a salmon. There are lions, tigers and 10 million bats, in a strong hour.

10) ALSO: PBS has its own mammal tales, rerunning from 8-11 p.m. Wednesday. It has the “Great America Recipe” finale at 9 p.m. today (rerunning at 9 Friday) and a portrait of changing Boston government at 10 p.m. Tuesday. Sunday has a new “Hotel Portofino” episode at 8 and the mid-section of “Magpie Murders” reruns, 9-11.
