Younger (10 p.m., TV Land and Nick Jr.) - A great new dramedy starring Broadway (and “Bunheads”) star Sutton Foster as a 40-year-old divorcee forced to re-enter the workforce after taking time off to raise her daughter (conveniently out of the picture because she’s a college exchange student in India). Foster lands an entry-level job at a publishing company, where all her young colleagues – and a handsome young love interest – assume she’s also in her 20s (she looks great). Hilary Duff plays one of Foster’s colleagues and Debi Mazar is Foster’s best friend and roommate. It’s from Darren Star, creator of “Sex in the City,” and despite the fact that there’s a tired “I’m going to die alone with a cat” joke less than three minutes into the pilot, it’s pretty irresistible. (And if you like this, do whatever you can to find the tragically canceled “Bunheads.”)
Also on tonight . . .
The Dovekeepers (9 p.m., CBS) - Part one of a miniseries based on Alice Hoffman’s fictional accounting of the siege of Masada and starring Cote de Pablo (Ziva from “NCIS”). Produced by Roma Downey and Mark Burnett. The conclusion airs Wednesday at 9.
Cancer: The Emperor of All Maladies (9 p.m., UNC-TV) - Part two of this Ken Burns documentary series focuses on the genetic basis of cancer and advances in research that lead to more precise therapies.
Weird Loners (9:30 p.m., Fox) - A new sitcom following four unmarried people who are thrown together by unfortunate circumstances and then form strange but sweet friendships. There’s an out-of-work cad (Zachary Knighton), a tragically single-in-her-30s dental hygenist (Becki Newton), a helpless man-child (Nate Torrence) and a detached artist (Meera Rohit Kumbhani). It’s not exactly funny, but after a few episodes, the loners – and the bonds they form – start to grow on you.
Justified (10 p.m., FX) – Raylan and the Marshals scramble to deal with a crisis that threatens all of their careers. Only two more episodes after tonight.
