Yorkey's book and lyrics match the probing compassion of Normal without indulging in that show's preciousness. The characters here are more accessible and likable, from James Snyder's rugged but tender Josh to Anthony Rapp's wry Lucas, Elizabeth's longtime friend. LaChanze brings infectious verve to the role of Kate, a lesbian schoolteacher who evolves from a stock comic-buddy type into a compelling individual. As for the leading lady, Menzel seems both grounded and energized by the opportunity to play a grownup who learns that there really are no ever-afters. There is poignance in that discovery, but a sense of liberation as well, and If/Then captures both to moving, invigorating effect.
