Manhattan Theatre Company premieres the latest from Pulitzer-winner (for Rabbit Hole) David Lindsay-Abaire, about a single mum from South Boston (Frances McDormand) recently out of a job and manipulating her way into a high school boyfriend's medical office to beg and manipulate. Not the most nuanced class warfare Broadway vehicle in recent memory, but McDormand and supporters Becky Ann Baker and Estelle Parsons make it very enjoyable.
