Except for Halston, who is incapable of not grabbing an audience, there’s little the cast can do to make this material feel full or fresh. Even Bonney, a director with miles of excellent productions to her credit — including “Mlima’s Tale” and “Cost of Living” — resorts to too many clichés. (The sound design, by Darron L West, and the projection design, by Elaine J. McCarthy, are especially obvious.) And a Hail Mary pass toward tragedy in the last moments of the play feels like an incomplete.
