Proof that one person’s “heartwarming” can be another’s emotional pornography can be found on “The Locator” (8 p.m., today, WE), now entering its second season.

Troy Dunn has made a career of reconnecting families torn apart by bad divorces and noncommunication.

He makes it his business to reconnect siblings who might have been literally separated at birth and then documents every tear, hug and sob for our entertainment pleasure.

In tonight’s show, a 26-year-old woman searches for her four sisters who have been scattered to the winds after being lost in foster care that was necessitated by their mother’s drug abuse.

• Over the next four weeks, Lifetime will turn over its Saturday nights to original movies based on the novels of Nora Roberts. Tonight’s offering, “Northern Lights” (8 p.m., today, Lifetime), stars Eddie Cibrian as a Baltimore cop reeling from the death of his partner.

What better place to regroup and lick his wounds than a town called Lunacy, Alaska?

There, he meets a feisty bush pilot (I am not making this up) named Meg (LeAnn Rimes). Who can blame them for finding love during those long nights of the northern latitudes? But when Meg’s dad — long-thought dead — ends up holed-up in a mountain cave, all bets are off! Rosanna Arquette co-stars as Meg’s mother and the long-abandoned wife of The Cave Man.

• Last Sunday, “Kings” (7 p.m., Sunday, NBC) debuted to mediocre ratings. I’ve long chastised NBC for programming cowardice, so I feel obliged to support them when they take a chance. A biblical parable/soap opera set in a modern fable, “Kings” is big and strange and different for network or even premium cable.

Viewers should give it a shot. And NBC should give viewers more chances to watch it by copying networks like HBO and repeating “Kings” several times a week, instead of say, “Celebrity Apprentice.” If a show this ambitious doesn’t find an audience, I suspect the NBC brass will use that as an excuse to broadcast more hours of “Howie Do It.”

On tonight’s “Kings,” David’s absence casts a pall over the peace talks.
