Mike Hughes on TV

1) “CSI: Vegas” finale, 10 p.m., CBS. Since its debut (shown here) in October, this has focused on a key story: Evidence suggests Hodges faked his lab work. His old friends (Grissom and Sidle) have been trying to show he’s been framed; if they fail, he’ll go to prison and countless convictions will be thrown out. Now – in the 10th and final episode of the season (and maybe the end of the series) – Hodges is missing. His friends desperately search for him. Read more…

1) “Abbott Elementary” debut, 9:30 p.m., ABC. A slow year for situation comedies is suddenly brightening. Too terrific ones get advance peeks – “Abbott” tonight and NBC’s “American Auto” next Monday – before getting weekly spots next month. Quinta Brunson (shown here) created this, produces it and stars as an earnest elementary-school teacher. Indeed, all the teachers here try hard, despite meager fundling and a clueless principal. The result manages to be both warm and funny. Read more…

1) “The Voice” semi-finals, 8-10 p.m., NBC. A week from the finale, “Voice” is down to eight acts – three on Blake Shelton’s team, two each with Kelly Clarkson and John Legend, only one with Ariana Grande. Now they perform and viewers vote; on Tuesday, five – tonight’s top four and one instant save – will advance. Tonight is all-music for NBC, with Michael Buble (shown here in a previous year) offering a special at 10, marking the 10th-anniversary of his best-selling Christmas album. Read more…

.1) “A Home for the Holidays,” 9:30 p.m., CBS (but 9 p.m. PT). There’s music starpower here, with Justin Bieber (shown here), Alessia Cara, Darren Criss and Kane Brown. And between songs, there are true stories of adoptions. We’ll meet a UCLA freshman who was in nine foster homes in her first 12 years. And a former adoptee who now has an adoptive son. And a family that had three biological siblings, then adopted a boy and his baby sister. We’ll also see a girl’s adoption being finalized. Read more…

1) “A Clusterfunke Christmas,” 7 p.m., Comedy Central. If you’ve seen a few Christmas movies, you’ll like this; if you’ve seen a lot of them, you’ll love it. It skillfully skewers their cliches, including the basic plot: A citydweller – accomplished, attractive, lonely – goes to a small town for a business deal … then discovers home-style warmth. Ana Gasteyer and Rachel Dratch (left and right) wrote a delightful script and co-star as the inn-owners. Vella Lovell stars (center), with Cheyenne Jackson as the hunky guy with an ax. Read more…

1) Football, 8 p.m. ET, ABC. It’s time for the conference championship games – two tonight and then nine packed into a busy Saturday. ABC has the big one, with the Oregon Ducks (10-2; their fan section is shown here) and Utah (9-3) colliding for the Pac-12 title. And at 7 p.m. ET, the CBS Sports Network has the Conference USA game: The University of Texas at San Antonio – which was undefeated until its loss Saturday – hosts Western Kentucky, which has won seven straight, after starting the season at 1-4.
