1) Basketball, 9 p.m. ET, CBS. The college tournament has been filled with wild twists and close games. Now we have the finals, with Jim Nantz, Bill Raftery and Grant Hill (shown here) at the mikes. A pre-game show is at 8:30 p.m. ET. In the Eastern and Central zones, that’s preceded (8 p.m. ET, 7 p.m. CT) by a fairly good “Big Bang Theory” rerun, with Leonard reluctantly in charge of grant money.
2) “Hostile Planet,” 9 p.m. ET, National Geographic, rerunning at 11:01. Human babies tend to get coddled, but some turtles don’t. Their first task in life is to spend hours getting through the sand and to the surface; their second is to dash to the sea, amid marauding birds and crocodiles. That stark sequence starts an hour that ends with stunning views of creatures at the bottom of the ocean. This sea-view hour is beautifully done … as was last week’s mountain-top opener, rerunning at 8 p.m. and 1:01 a.m. ET.
3) “American Idol,” 8-10 p.m., ABC. On Sunday, half the top-20 singers did duets with celebrities. Now the other half get a chance, with a different set of celebs. There will be two duets apiece for Ben Harper, Julia Michaels, Lukas Graham, Chris Isaak and Tony-winner Cynthia Erivo.
4) “Independent Lens,” 10-11:30 p.m., PBS. Others may flee to bigger cities and higher pay, but Matt Probst says he never considered it. “I love this community.” He got a physician’s assistant degree and returned to Las Vegas, a New Mexico town with 13,000 people and a staggering economy. Now he’s the medical director of a clinic. This slow but involvig film follows him, Dr. Leslie Hayes and nurse practitioner Chris Ruge as they bring one-on-one care, while scrambling to find and retain staff.
5) “Queens of Mystery,” any time, www.acorn.tv. Fresh from her brilliant double role in “The Woman in White,” Olivia Vinall plays a police detective whose three aunts all write crime novels. There’s a prompt murder, of course; ignoring all warnings to stay out of the way, the aunts plunge in. The result is great fun, with a zesty look and feel. The aunts will tackle more murders on the next two Mondays.
