Nashville guys and their special friends

Now in its second season, “Girls Who Like Boys Who Like Boys” (8 p.m., Sundance) moves to Nashville. So the capital of country music in the heart of the Bible Belt becomes an unlikely setting for a reality series about the relationships between straight women, married and unmarried, and their gay male best friends.

Docu-soaps come in several varieties. There’s the anthropological approach first employed in “An American Family.” There’s the dumb and depressing human train-wreck style of “Jersey Shore.” Or the personality-as-product- placement technique that Bravo tends to favor.

Kristin and Peter provide the show’s most touching moments. Peter has three kids from a marriage that fell apart when he came out to his wife. Kristin relies on Peter for companionship while her husband is deployed in Afghanistan. Peter’s kids also love Kristin like an aunt or extra mother, and this makes Kristin feel good because she can’t wait to have children of her own. This is the part of the show where viewers can ponder the very nature and definition of “family.”

But before things get too educational, there’s Tenisha and Jared, a black woman and a white Mormon gay man who share a connection that is both affectionate and combustible. Their arguments provide the kind of screaming scenes Sundance can use to promote this show to lowbrow fans of coarse reality fare.

Sherrie and Shane seem to be in it for the publicity. At least Sherrie. She’s an Australian-born former actress who appeared on “The Facts of Life” and who wrote a few hit songs. She wants to make a comeback as a singer-songwriter. Think a stint on a TV show will help her get noticed? Her gay friend Shane has also had success as a songwriter for Lady Antebellum and other artists. Shane and Sherrie seem to agree on everything, except maybe Shane’s overt religiosity, which makes Sherrie a little uncomfortable.

Olivia and Brent round out the group. They’re starting a party and event planning business for Nashville’s posh people. And what would a reality show be if somebody weren’t arguing about an A-list seating arrangement?
