1) “World of Dance” finale, 8-10 p.m., NBC. Last week, the show picked its four divisional winners. Now they compete for the million-dollar top prize, alongside one wildcard pick. In the first two seasons, that prize went to hip hoppers; this time, both of the team winners are hip hop – Vpeepz, from the Philippines, in junior (17 and younger), the Kings, from India, in upper. For small groups (1-4 people), both winners are contemporary – Ellie & Ava (shown here), junior; and Briar Nolet, upper.
2) “American Idol,” 8-10 p.m., ABC. The final six performers each do two songs – one that was done at Woodstock, 50 years ago, and another that’s considered an inspirational showstopper. Lauren Daigle will be the mentor and Gabby Barrett – who finished third last year – will perform her single, “I Hope.”
3) “Good Girls,” 10 p.m., NBC. “I wanna be normal again,” Beth announces. She’s had enough of the drug-mule schemes; she wants to get back to book clubs and cookie-baking. Or does she? One scene, as she returns from a PTA event, paints powerful emotions.
4) “The Red Line,” 8-10 p.m., CBS. On most levels, this is a beautifully layered look at the tentacles of pain, after a Chicago cop shot a doctor, mistaking him for a robber. The one big flaw involves the fact that the cop’s partner secretly stole the tape from the security camera. It makes no sense that she kept it … or that she told him about it … or that he then stole it and lost it. Tonight, the impact grows.
5) Much more. Tonight brings a debut — “The Spanish Princess” (8 p.m., Starz) profiles the woman who married Prince Arthur and, after his death, his brother King Henry VIII – and a return: “When Calls the Heart” (9 p.m., Hallmark) disappeared for seven weeks, while Lori Loughlin was being edited out. Also, there are fairly good episodes of “Les Miserables” (9 p.m., PBS), with Collette seeing the harsh outside world; and “The Chi” (10 p.m., Showtime), with a funeral for Kevin’s dad.
