A selective critical checklist of notable Monday TV:

America’s Got Talent: The Champions (8/7c, NBC): Viewers clearly have an appetite for high-concept reality TV this winter, with strong opening numbers last week for Fox’s ridiculous The Masked Singer and NBC’s Dwayne Johnson-fueled The Titan Games. So hopes are high as NBC spins off its hit summer talent show with an international edition, featuring fan favorites from past seasons and breakouts from international versions of Talent. With Brooklyn Nine-Nine’s Terry Crews as host, 10 acts compete in the opening episode for judges Simon Cowell, Mel B, Heidi Klum and Howie Mandel. Two will advance to the finals: one with a Golden Buzzer, and another sent on by a panel of AGT super-fans.

Fifty former finalists and winners from across the globe will compete on the same stage for the title of ultimate champion.

The Bachelor (8/7c, ABC): The twice-yearly wallow in made-for-TV romance kicks off with a typically indulgent three-hour live special, featuring cutaways to “Bachelor Nation” viewing parties from across the party. (You know who you are.) Colton Underwood is the BMOC choosing among an initial gaggle of 30 hopefuls, who will be reduced to 23 by night’s end.

Antiques Roadshow (8/7c, PBS, check local listings at pbs.org): Gearing up for its 23rd season of treasure hunting, PBS’s most popular ongoing series promises “an all-new look,” as it hits the road to visit historic venues. First stop: Rochester, Michigan, where valuables are appraised at Meadow Brook Hall, the estate of Matilda Dodge Wilson.
