Weekly Previews

1) “Big Brother” season-opener, 8 p.m. Wednesday, Thursday and Sunday, CBS. Ever since 2000, this has propelled CBS’ summers, mostly becoming a playground for young people who are telegenic and assertive. Tonight, it’s paifed with “Love Island” (shown here), each with a 90-minute opener. On “Big Brother,” we’ll meet eight women; one is a 40-year-old phlebotomist, but the others range from a 21-year-old grad student to two women who are 30. We’ll meet eight men; a farmer is 34, the others are in their 20s. The house also has a lawyer, a scientist, a teacher and lots of salesfolks. Read more…

1) “A Capitol Fourth” (shown here), 8 p.m. Sunday, PBS, rerunning at 9:30. This should be a festive night for a re-opening world, with performances spanning the country. It will be Alan Jackson in Nashville; Jennifer Nettles and Auli’i Cavalho in New York; Jimmy Buffett, Cynthia Erivo, Pentatonix and Train in California. In Washington, D.C., will be fireworks, plus the National Orchestra, Gladys Knight, Mickey Guyton, Jimmie Allen, Ali Stroker, Laura Osnes and (doing the National Anthem) Renee Fleming. Read more…

1) “Making It” season-opener, 8 p.m. Thursday, NBC. It’s been a long wait for one of TV’s best competition shows. The first two seasons brought Emmy nominations for its hosts (Amy Poehler and Nick Offerman, shown here) and a Television Critics Association nomination for best reality show. Then came an 18-month shutdown. But now it’s back, with likable contestants (taxidermist, muralist, etc.) making projects that have personal links. “So many tears in episode one,” Poehler says. And quite a few laughs. Read more…

1) “The Republic of Sarah” debut, 9 p.m. today, CW. In this New Hampshire town, nestled against the Canadian border, life is quiet and autumn is gorgeous. Then heavy equipment rolls in; everything will change. The real plot doesn’t click in until the second half of this hour; “Republic” toys with our first assumptions about Sarah and others. We won’t spoil any surprises; just expect some neat twists. The villains here are absurdly overdrawn, but Sarah (newcomer Stella Baker, shown here) is immensely likable. Read more…

1) “The Bachelorette” opener, 8-10 p.m. today, ABC. Now the annual summer leaders are in place – “Bachelorette” on Mondays, “America’s Got Talent” on Tuesdays. Last year, “Bachelorette” was delayed until fall and did well; this year, it gets both – Katie Thurston (shown here) now, Michelle Young in September. Thurston, 30, is older than at least 20 of the 30 men she’ll meet. They range from a deputy district attorney to two athletes and a zipper sales manager. Tayshia Adams and Kaitlyn Bristow host. Read more…

1) “America’s Got Talent” opener, 8-10 p.m. Tuesday, NBC. We’re in the summer season now – a time when “AGT” dominates the ratings. It slipped a bit last year, with remote performances; now it returns to onstage auditions … and Simon Cowell (shown here) returns after an injury. At first, traditional acts kept winning; five of the first six champions were singers, alongside one ventriloquist. Since then, however, the winners have included only two singers, plus two more ventriloquists, a magician, a dancer, a dog act and, last year, a spoken-word poet. Read more…

1) “The Voice” finale, 8-10 p.m. today and Tuesday, NBC. This will revolve around Blake Shelton – as life often does. He has two of the five finalists, Jordan Matthew Young (shown here) and Cam Anthony. (The others are Victor Solomon, Rachel Mac and Kenzie Wheeler.) His fiancee Gwen Stefani will be there, singing with Saweetie; so will his friend Adam Levine, with Maroon 5. Other performers Tuesday: Justin Bieber, Thomas Rhett, OneRepublic, Kelsea Ballerini, Snoop Dogg, Ben Platt and Lauren Daigle. Read more…

1) “American Idol” finale (ABC) or “Billboard Music Awards” (NBC), both at 8 p.m. Sunday. To complicate our lives, two pop-music events are simultaneous. “Idol” is down to its final three now and is ready to choose a champion. Billboard has Nick Jonas hosting and Pink and The Weeknd performing. Drake (shown here) – who has had nine No. 1 singles – gets the artist-of-the-decade award. He and Weeknd are up for artist of the year, alongside Taylor Swift, Pop Smoke and Juice Wrld. Read more…

1) “Mom” series finale, 9 p.m Thursday., CBS. At times, this has been TV’s best comedy, a dandy blend of quiet emotion (as recovering alcoholics cope with life) and loud humor. The latter part is propelled by by Bonnie’s unapologetic adventures. Allison Janney (shown here with William Fichtner) has mastered the role, winning two Emmys and three more nominations – to go with four Emmys and an Oscar elsewhere. Now some news gives Bonnie a new outlook on sobriety. And Jill and Andy, now re-connected, take a big step. Read more…

1) “The Voice” (shown here), 8-10 p.m. today, NBC. In a sudden surprise, this ratings-leader has the night to itself. It had been competing with “American Idol,” and winning by 3-2 margins. (“Voice” ratings have dropped 10 percent this year, but “Idol” on Monday is down 27 percent; in the 18-49 age groups, the drops are steeper.) Now “Idol” has been pulled from Monday; it’s Sundays-only, concluding May 23. Tonight, with 16 of its final 17 chosen, “Voice” will pause to review the season and the 19 previous seasons. Read more…
