“Ms. Molina, who played Johanna to perfection in the 2005 Broadway revival of Sweeney Todd, is something else again, a quirky, angular beauty with a sharp-edged sense of humor whose limbs look as though they’re made of taffy. I last saw her on stage four months ago in the San Diego premiere of “Nobody Loves You” and delighted in her comic energy. She’s just as funny in “Marry Me a Little,” but what you’ll remember here is the intense wistfulness with which she puts across Mr. Sondheim’s famously ambivalent ballads (“Keep a tender distance / So we’ll both be free / That’s the way it ought to be”). Not only does she nail the title song, but I’ve never heard a more affecting performance of “There Won’t Be Trumpets.” Might Ms. Molina be poised for musical-comedy stardom? It certainly looks that way.”
