1) “The Voice” finale, 8-11 p.m., NBC. It’s time for the 22nd champion … eventually. At 8 p.m. is a recap of previous performances; from 9-11 p.m. is a surge of music — Blake Shelton with his three finalists (Brayden Lape, Bryce Leatherwood, Bodie) and with Kane Brown (shown here). Camila Cabello and John Legend sing with their finalists, Morgan Myles and Omar Cardona. Also: Kelly Clarkson, Adam Lambert and more, including the previous winner (shown here), the sibling trio Girl Named Tom.
2) “O Holy Night: Christmas With the Tabernacle Choir,” 8 p.m., PBS. After missing a year because of Covid, the mega-concert returns. Broadway’s Megan Hilty and actor Neal McDonough are surrounded by 500 people, including choir, orchestra and bell-ringers. The emphasis is lassical – Hilty sings only once in the first 20 minutes – and subdued. But the result, beautifully filmed, teems with grandeur.
3) “CMA Country Christmas,” 9 p.m., ABC. This reruns an hour sparked by great instrumentalists. There’s a dandy house band (with strong horn section) and Molly Tuttle’s bluegrass group. Singers include host Carly Pearce, Scotty McCreery, Maren Morris, Old Dominion, and Dan + Shay. Providing variety to the peppy-music night are passionate songs by Steven Curtis Chapman and War + Treaty.
4) “FBI” shows, 8-11 p.m., CBS. In a week when new, scripted shows are rare, CBS gives us three of them. On “FBI” (8 p.m.), a teen shows up with a bag of fentanyl, seeking protection form the men who shot his father. On “FBI International” (9), Vo goes undercover after an American model dies in Milan. On “FBI: Most Wanted,” three prosecutors are assassinated outside a small-town bar.
5) “Avatar: The Deep Dive,” 10 p.m., ABC. In the 25 years since his “Titanic” became the first billion-dollar hit, James Cameron has directed exactly one scripted movie for theaters, the 2009 “Avatar.” Now that film’s sequel, a three-hour-plus monolith, arrives Friday, with three more in the works. It continues to star Sam Worthington, Zoe Saldana and Sigourney Weaver, adding Kate Winslet and Edie Falco. This hour looks at the film, stars and director.
