Ann Marie-Duff was great with emotional vulnerability and underlying strength. Stephen Campbell Moore and Dominic Rowan were relatively one dimensional. The reconfigured seating arrangement with sand filled stage and a long hanging staircase above the stage was interesting but not entirely clear as to how it fits into the story. Maybe the precariousness of heights, drifting of time with the falling sand, etc. The play itself is dense and exploration of love and circumstances. There is just about enough to keep one’s interested.
