Zach Anner is the most engaging personality on a network that needs them badly. The host of the travel show “Rollin’ With Zach,” which has its premiere on Monday night on OWN, the floundering Oprah Winfrey Network, with two episodes, he’s witty and charming and mildly zany.

And also disabled. Mr. Anner has cerebral palsy — “the sexiest of the palsies,” he says in the show’s intro, a joke repurposed from his audition tape for the reality competition “Your OWN Show: Oprah’s Search for the Next TV Star,” which ran earlier this year, and of which he was one of two winners. (“The Ambush Cook,” the show of the other winner, Kristina Kuzmic-Crocco, had its premiere this month.)

The Oprah Winfrey Network has been on for almost a year and has tended toward the sorts of self-help pablum that sounds great coming from the mouth of Ms. Winfrey, but it has otherwise offered quickly diminishing returns.
