‘UNICORN’ FOLLOWS LONG TRADITION OF MOTHERLESS TELEVISION

— In this era of sitcom remakes, "The Unicorn" (8:30 p.m., CBS, TV-PG) can call itself original. But it hearkens back to one of TV’s greatest, and weirdest, traditions: killing off mommy.

For the uninitiated, "Unicorn" stars Walton Goggins ("The Shield," "Justified") as Wade, the father of two cute adolescents, all recovering from the death of his wife and their mother. The title refers to a term related to adult dating or online, app-driven dating. His status as a stable, dependable, long-married man without baggage and without a living "ex" in the picture makes him a rare and desirable commodity.

The show modulates between his mournful mindset and the efforts of his friends to catapult Wade back into the dating scene. Tonight’s Thanksgiving episode puts the accent on the misty moments as his daughters try to re-create a sweet potato casserole recipe that was a favorite of their mother’s.

At least four of the most popular series of the classic TV era — "Bonanza," "The Beverly Hillbillies," "The Andy Griffith Show" and "My Three Sons" — were variations on the theme of absent mothers. Other less popular but no less classic series, from "Family Affair" to "Nanny and the Professor" and "The Courtship of Eddie’s Father," followed suit, consigning mothers to the grave.

The trend returned with a vengeance a generation later, with "Diff’rent Strokes," "Punky Brewster," "My Two Dads," "Full House," "Who’s the Boss?," "Gimme a Break!," "Blossom" and others.

What’s a mother to do? Why die, of course, preferably before the pilot episode.

Some viewers may balk at accepting Goggins in this rather heart-tugging role, having grown used to him in more sophisticated series as a villainous character or at least a charmer with a flash of menace in his eyes.

On the other hand, sitcoms can reflect an actor’s versatility. At the same time he was starring in "My Three Sons" and silly Disney "Flubber" movies, Fred MacMurray played one of the greatest screen heels of all time in Billy Wilder’s "The Apartment." He had also played a scheming killer in Wilder’s "Double Indemnity." That’s quite the range.
