NBC kicks off its new musical competition “The Voice” (8 p.m., NBC). Judges Christina Aguilera, Cee Lo Green, Adam Levine and Blake Shelton evaluate talents at a blind audition. Each judge chooses eight performers to mentor as they vie for a grand prize of a recording contract and $100,000. Carson Daly hosts.

“The Voice” certainly has some competition. “Glee” (7 p.m., Fox) offers a 90-minute episode celebrating the music of Lady Gaga. And over on ABC, a new contestant gets voted off “Dancing with the Stars” (8 p.m., ABC).

• Looking for something completely different? “Independent Lens” (9 p.m., PBS, check local listings) presents the documentary “Marwencol,” a film as strange and intriguing as its title.

Beaten savagely outside of a bar in Kingston, N.Y., Mark Hogancamp awoke weeks later with no clear memories of his past. He had photographs of an ex-wife he could not recall and a journal in his hand, filled with elaborate drawings as well as the angry musings of a depressed alcoholic.

Dismissed from hospitals and treatment facilities for lack of money, Hogancamp would devise his own particular kind of therapy. No longer able to draw and devoid of any desire for alcohol, he created an elaborate backyard fantasyland consisting of a fantastically detailed World War II-era Belgian village (named Marwencol), peopled by uniformed toy soldiers and attractively garbed Barbie dolls.

Hogancamp based the characters in his imaginary village on friends, neighbors and former co-workers and staged scenes of both violence and friendship — scenarios that often mirrored his emotional state.

A film as unique and strange as its subject, “Marwencol” offers a peculiar meditation on memory and loss and the redemptive, or at least revelatory, power of the imagination.

• Spike premieres “Repo Games” (7 p.m. and 7:30 p.m., Spike). Modeled on “Cops,” it follows professional repossessors as they go to homes where customers have fallen behind on car payments. But instead of hauling off the vehicle, they offer the unfortunate person a chance to win back the car and its title free and clear. All they have to do is correctly answer three out of five trivia questions (and presumably agree to have this moment air on television for our entertainment pleasure).

• DVDs available today include the BBC miniseries “Human Planet.”
