Tune in Tonight: ‘Billy & Molly’: Otterly delightful

Blending two very different documentary styles, “Billy & Molly: An Otter Love Story” (10 p.m., National Geographic, TV-G) has won the hearts of film critics and festival audiences.

On one hand, it has all the stunning cinematography and stirring music of a nature documentary, capturing the gorgeous scenery of Scotland’s Shetland Islands as well as their delicate environment and aquatic diversity. But at its core, it is an intimate love story about two wounded strangers who find each other and nurse each other back to health.

When Billy Mail and his wife, Susan, relocated to the remote island, Susan was a bit worried about her husband. He seemed at a loss. Then, seemingly from out of nowhere, a similarly lost otter began to act very tame around Billy. Soon named Molly, the otter appears to have lost her family and needed company.

Billy obliged with all the enthusiasm of the late-middle-aged hobbyist, taking up fishing to keep Molly well-fed and building a special otter dollhouse and outfitting it with cameras and the necessary Wi-Fi to transmit all of his doting footage. Susan points out that Molly has better Wi-Fi than she does!

Given the lush photography, “Molly” must be taken with a bit of suspension of disbelief. It’s not just any critter lover who gets to be captured by experienced nature cinematographers like Charlie Hamilton James (“One Life”), Johnny Rolt (“Britain’s Scenic Railways”) and Bertie Gregory (“Animals Up Close”). The score was composed by Erland Cooper (“Is There Anybody Out There?”).

We can all be forgiven for surrendering to this romantic fable. In a reality-TV-obsessed world where people submit to the contrived indignities of “Deal or No Deal Island” (10 p.m., NBC, TV-PG), it’s nice to know that true love is still out there. Even if it has to swim vast cold oceans to find you.
