...after a slow start, White's play (jointly produced by Manhattan Theatre Club and MCC Theater) evolves, under Daniel Sullivan's meticulous direction, into a lovely, moving account of a clan's struggle to adapt to trying circumstances and a changing world. White's Broadway debut, The Other Place, produced earlier this year, also followed a middle-aged woman whose grasp on reality was challenged, but it was a psychological mystery that blurred lines between past and present, imagination and fact. This more conventionally structured study of unlucky souls seems to have been written under Chekhov's spell.
