Critic Scorecard
10 reviews“It's been a long time since Broadway has seen the debut of a new play the quality of Proof, and even longer since it has welcomed the debut of a new playwright as talented and promising as David Auburn.”
“I wish I could tell you why that play is among the best of the season—but believe me, it truly is.”
“Together, Bryggman and Parker hit enough emotional highs to sustain a dozen lesser plays.”
