Good people, or just unlucky?

​Good People, David Lindsay-Abaire’s play set in both working-class South Boston and upper-class Chestnut Hill, is having its local premiere at the Old Globe’s Sheryl and Harvey White Theatre. It’s intended to be a biting commentary on the class divide, though it never decides whether it wants to bare its teeth or be a salty quip-fest around the bingo table. Its characters – the bingo-playing “Southies” and the lace-curtain Chestnutters – are rather unlikable, though Robin Pearson Rose’s Dottie the landlady is like out of an R-rated episode of “The Golden Girls.” Struggling single mother Maggie (Eva Kaminsky) is so desperately short on self-esteem and self-respect that she inspires pity more than sympathy, especially in Good People’s more confrontational second act.
