The actors conveyed what the space and set lacked with their performances. They built the world around them.
What I didn't like
Some directorial choices were odd to me. Not sure why Roberta was folding clothes in the morning, clothes that had been strewn across the set. Something about it lacked authenticity for me. In a show that is already so stripped down, everything has to be calibrated accordingly.
My overall impression
Stripped down and diminished but it maximized the effect. The performances were real and raw.
