It would also be easy to attribute the improvement to Neugebauer’s direction, which is so smart and swift for most of the play’s substantial length that you feel gripped by storytelling without being strangled by argument. Her staging, on a towering double-decker set by the design collective dots, is also nearly ideal, accentuating (with the help of Jane Cox’s painterly lighting) the conflicts and alliances among the characters. And the daredevil cast, instead of reveling in falling apart, focuses for as long as possible on keeping it together. We thus experience, in the force of that repression, just how awful human awfulness must be if human will cannot ultimately corral it.
