NBC streaming service Peacock is throwing its hat into the Christmas movie ring with a brand-extending concept: take sister network Bravo’s realest housewives and allow them to ruin Christmas for anyone who gets in their way. That seems to be the promise of “Real Housewives of the North Pole,” starring “Real Housewives of Beverly Hills” glamourpuss Kyle Richards and “Breaking Bad” alum Betsy Brandt. They’ll play two women who’ve won the holiday house decorating contest for a decade in the town of North Pole, Vermont, only to find themselves in a knock-down-drag-out, friendship-ending fight that splits the town into feuding factions. Shooting soon, we want this fight before Christmas on our screens by December if only to spill a little corrosive acid on the cozy genre that seems to dominate TV for the last hundred days of the year.
