What's Worth Watching: Little Big Shots, The Carmichael Show, And Then There Were None and more for Sunday, March 13

Little Big Shots (8/7c, NBC): Steve Harvey's star continues to rise, now in prime time, with a family-friendly vehicle that gives him free rein to work his genial wit alongside pint-sized show-stoppers. Following Tuesday's preview (replayed at 7/6c) that attracted more than 12 million viewers, Little Big Shots settles into its regular time period with Harvey introducing a 4-year-old piano prodigy, two precociously talented pre-teen salsa dancers and a 6-year-old conductor who's likely to show the host some moves.

The Carmichael Show (9/8c, NBC): A sitcom family debates the legacy of Bill Cosby, who once upon an era was TV's most beloved sitcom dad, in a startling, stinging and very funny episode of last summer's sleeper comedy. This is a great way to launch a midseason run, with biting writing more than compensating for the bland central performance by title star Jerrod Carmichael. When Jerrod's girlfriend (Amber Stevens West) refuses to go along to a Cosby concert, he tries to interest his parents (Loretta Devine, David Alan Grier, the show's best assets), making the provocative argument: "Talent is more important than morals." The fact that this is airing on the network whose "Must-See-TV" era was ignited by the Cosby Show phenomenon is staggering.

And Then There Were None (9/8c, Lifetime): Agatha Christie's most ingenious mystery-thriller gets the adaptation fans have long awaited in a deluxe, all-star miniseries in which eight strangers (and two creepy servants) gather in a remote island mansion where they're offed one by one by a malicious unseen host. Among the not-so-innocent targets: Aidan Turner, Charles Dance, Sam Neill, Miranda Richardson, Toby Stephens, Burn Gorman and Anna Maxwell Martin. Concludes Monday.

Inside Sunday TV: Time to set your brackets, once CBS lays it all out in the annual NCAA Basketball Championship Selection Show (7/6c). … In an episode titled "Dead Or Alive," candidates assess the viability of their campaigns after another tumultuous and potentially pivotal week, on Showtime's The Circus: Inside the Greatest Political Show on Earth (8/7c). … Human monsters often present a greater peril to our heroes than the zombies on AMC's The Walking Dead (9/8c), and so it is when Carol (Melissa McBride) and Maggie (Lauren Cohan) are taken prisoner by the new enemy.
