One doesn't usually seek out sequels at live theatre, and when Ibsen finished his masterpiece A Doll's House in 1879, one can only assume he thought the interesting part of the story was over. So the pressure on this play to prove why it should even exist is almost like another character watching from the wings. Thankfully, what Lucas Hnath has written is a smart and occasionally hilarious play that justifies its creation, and ties the hands of almost all characters equally. There are plenty of satisfying revelations, and Gamm's excellent cast makes this a show not to be missed.
