(Caveat: at the performance I saw, not one, but two, women crumpled plastic bags on and off for the whole 100 minutes. They were really annoying, and they made it impossible to concentrate fully. So take this review with however many grains of salt you consider appropriate.)
The play also has a fifth character, Vivian, an African-American girl in her early teens who doesn't interact with the others, speaking to the audience directly.
And then there's Vivian, who exists unmoored in the play. She comes onstage, she talks, she leaves. On, talk, off. On, talk, off. We eventually find out who she is and where she fits in, but for most of the play, her lack of grounding is disturbing. However, Danielle Thompson's performance is amazing; she develops Vivian fully, tells stories well, and brings everyone she talks about to life.
Director Hill unfortunately lets the pacing lag, particularly between scenes; after the fifth or sixth scene change, the musical intervals become irksome. Hill's blocking is also problematic; in certain scenes, particularly between George and Helen, the characters seem unanchored, with no physical reality. The set, by Roman Tatarowicz, is attractive, but may contribute to the lack of context. On the other hand, the projections, by Kevin R. Frech, work well, adding a sense of the bigger issues and concerns.
I feel a bit churlish in this review; there is good work in this show, and a great deal of talent. But the whole is less than the sum of the parts.
