NBC’s new reality show “The Baby Borrowers,” really isn’t any worse than the other shows in the genre, says Tom Shales in the Washington Post. Teen-age couples are given a baby, a toddler, a pre-teen, an adolescent and a geezer to care for over the course of six episodes to see how they function as parents. Eventually the unreality of reality sets in because the contestants aren’t the only ones who know they’re in a TV series. “Whatever credibility the show has built up tends to dissipate simply because the arriving kids are media savvy enough to play to, and for, he camera virtually every moment,” Shales says.
