Mike Hughes on TV

1) “World of Dance,” 10 p.m., NBC. Here’s the second half of the “duels” in the senior category, with sharply contrasting styles. Some have catchy gimmicks – a duo tethered together, sometimes breaking apart; a group that does wonders with arms and hands and even a bouncing chin. Others (including Oxygen, shown here) are high-energy dance. Two advance, joining last week’s three winners; then two of the five losers get a shot at the final spot. Amid way too many cliches, there are some great dance moments. Read more…

1) “CMA Best of Fest,” 8-11 p.m., ABC. Each summer, ABC turns Nashville’s CMA Fest into a terrific special. This year’s festival was canceled, but the special continues. There’s new music from Luke Bryan (shown here), who hosts, and from Darius Rucker; others will be shown in bits from 16 previous years. We’ll get newer stars (Luke Combs, Kane Brown, Kelsea Ballerini) and A-list veterans – Garth Brooks, Blake Shelton, Carrie Underwood, Brad Paisley, Miranda Lambert, Keith Urban, Brooks and Dunn and more.

1) “Snowpiercer” season-finale, 9 and 9:58 p.m., TNT. As the current heat wave grips much of the country, here’s the exact opposite: The temperature outside is minus-122 Celsius, which is worse than it sounds; in Fahrenheit, we’re told, that’s minus-188, People are safe only as the train keeps moving. But inside the train, Daveed Diggs and Jennifer Connelly (shown here) battle for control. And outside, there are potent new forces. It’s a tautly crafted finale, but don’t expect an ending. Mostly, this propels us to next season. Read more…

1) “Saturday Night Live,” 11:29 p.m., NBC. It was beefy-guy night, when this aired on Super Bowl eve. JJ Watt, 6-foot-5, 288, hosted; Luke Combs, 5-8, 198, sang (shown here). Watt is a pro football star – three times named defensive player of the year. Combs played football in high school, but then soared as a singer. He’s quicklty had eight songs reach No. 1 on the country chart; “Beautiful Crazy” stayed for seven weeks. Here, he offers the important musical message: “Beer Never Broke My Heart.” Read more…

1) “American Masters: Unladylike,” 9 p.m., PBS. This summer’s PBS shows have been propeling us toward a milestone – the 100th anniversary (Aug. 26) of women’s vote in federal elections. But before the national change, individual states stepped in. We meet Dr. Martha Hughes Cannon, who was elected in 1896 to Utah’s state senate and sparked health reforms; her statue (shown here) is alongside the state capitol. And Jeannette Rankin, elected by Montana to Congress in 1916. It’s a strong hour that also includes black, Latina and American Indian activists. Read more…

1) “In the Dark” season-finale, 9 p.m., CW. For the second straight season, “Dark” started slowly and built to a crescendo. Murphy (who is blind) and friends have until midnight to find and return the drugs Ben stashed before his death. Now they collide with Dean (the crooked ex-cop), who also wants the drugs. This has a too-long detour that strains believability, but then wraps things up powerfully … and propels us toward next season. Despite its flaws, “Dark” has subtly gifted actors (especially Perry Mattfeld and Brooke Markham, shown here, as Murphy and Jess) in a gripping story. Read more…
