Lighting was used effectively to transition from flashback to the present day, and the intimate black box setting added to the tension as the night slowly unravels. As mentioned, great acting from everyone, with Erin doing double-duty as both writer and performer, in which she excels at both.
What I didn't like
Not much can be improved upon here.
My overall impression
As someone who has seen this play workshopped while in its earlier stages, it was a joy to see it come to life in full at The Broadwater. Wonderful use of lighting. Stellar acting from everyone, as well as stellar writing. All and all incredibly well-executed.
