1) “Gidget” (1959), 9:45 p.m., Turner Classic Movies, and more. On the first full day of summer, TCM has a spree of summer movies (see separate story, above). “Gidget” is partly old-school — sweet girl, warm family — and partly new, with a teen (Sandra Dee, shown here) who surfs with the guys. Other summer settings are in Betty Grable’s “Moon Over Miami” (1941, 8 p.m.), the French comedy “Mr. Hulot’s Holiday” (1953, 11:30), the Bogart-Bacall “Key Largo” (1948, 1:15 a.m.) and Andy Hardy’s “You’re Only Young Once” (1938, 3:15 a.m.).
2) “American Ninja Warrior,” 9-11 p.m., NBC. After being bumped by the Olympic trials last week, “Warrior” is back. It’s nudged back an hour, to make room for track-and-field trials at 8.
3) “The Republic of Sarah,” 9 p.m., CW. In last week’s opener, an idealistic young teacher battled a company. She found a treaty glitch that allowed this New Hampshire town to declare its independence. It was a terrific hour, marred only by the cliché villains – including her brother (who works for the evil company) and some FBI agents who (in an absurd scene) arrested her. Now she settles into the headaches of leading a country … including the fact that the power has been shut off.
4) “Celebrity Dating Game,” 10 p.m., ABC. The second episode has Carson Kressley (of the original “Queer Eye For the Straight Guy”) and Iggy Azalea (the Australian rapper), looking for love. That follows a “Bachelorette” (8-10 p.m.) with Katie Thurston and some of the guys telling personal stories.
5) “Whitstable Pearl,” any time, www.acorn.tv. The first-season ends with a murder story that hits hard on Pearl, reflecting the mixed views of her late father. It’s a serious hour, with Australian accents that require viewers’ full attention. If you just want to relax and have fun, Acorn also has a new hour of the breezy “Ms. Fisher’s Modern Murder Mysteries.” Amid the cheery, ‘60s-Aussie atmosphere, we find dark doings at a dog show.
