I loved the pacing and the use of light to make a scene and ratchet up the tension. Ending was a shock!
What I didn't like
Some of the dialogue got a little plodding near the middle/end. I think that it could be shortened a little without taking away from the gravity of the scenes.
My overall impression
Amazing energy without paise by both actors; subject matter is powerful and salient to our current social and political climate.
