1) “Cruel Summer” season-opener, 9 and 10 p.m., Freeform. The first season was a surprise – a teen drama with subtlety and depth. Now the second one has new characters in a new setting, but the same quality. Sadie Stanley (who was Brea, Adam’s girlfriend in “The Goldbergs”) is perfect as a brainy kid in a pleasant town. Then a worldly exchange student (Lexi Underwood of “Little Fires Everywhere,” shown here, left, with Stanley) stirs her quiet world, over two summers and a winter.
2) “Stars on Mars” debut, 8 p.m., Fox. They’re not really on Mars (budget restrictions, you know), but on a set. Getting instructions from William Shatner, 92, they colonize it. Some are athletes — fighter Ronda Rousey, cyclist Lance Armstrong, figure-skater Adam Rippon and football’s Richard Sherman and Marshawn Lynch. Others include comedian Natasha Leggero and Tallulah Willis, the daughter of Bruce Willis and Demi Moore.
3) “American Ninja Warrior” opener, 8-10 p.m., NBC. Last week, “Ninja” showed a women’s championship that it filmed last year. Now it launches its 15th season; two rounds will be in Los Angeles, with the finals in Las Vegas, To get there, contestants must clear six obstacles in a prescribed time, including an 18-and-a-half-foot wall. “Ninjja” alsoreruns at 7 p.m. Sunday.
4) More unscripted. At 9 p.m., Fox has “Crime Scene Kitchen”; at 10, NBC has “Weakest Link” (this time with eight drag queens). And all night, ABC has “Celebrity Family Feud.” There are individual celebs – Leggero, Nathan Chen, Kristin Chenoweth, Simu Liu, etc. – plus the casts of “Shark Tank,” “The Talk,” “Summer House” and “My Unorthodox Life.”
5) “Mission Impossible: Rogue Nation” (2015), 8-11 p.m., CBS. Yes, modern movies can succeed strictly via action and special effects. Still, Tom Cruise has tried to make sure he also has a good script. This is the third of eight Cruise films written by Christopher McQuarrie, the “Usual Suspects” Oscar-winner. That includes “Top Gun: Maverick” and a “Mission Impossible” film opening next month.
