I liked the simple stage set up. The actors used the space to their advantage with great transitions and poses of power.
The chemistry between the actors was fantastic. Like watching a tennis match.
What I didn't like
I felt that for the 3rd act: the professor could have looked a bit more disheveled (undoing a button and messing up his hair) considering he didn’t go home in 2 days.
Other than that tiny detail, I was really moved by this performance.
My overall impression
Fantastic performances from both actors. Great pacing, edge of seat stuff!
