I was very impressed by the filming of the final scenes in the tube. The logistics of this reminded me of The Bourne Supremacy. I wonder how many extras were involved in the production? Also I saw a promotional poster of The Lincoln Lawyer in the tube.
Also one of the compelling characters is Alice Fox who comes across as a feisty supporter of lesbian rights with a major chip on her shoulder, and would prefer to dwell on racial injustices rather to detract from the suppression of LGTBI fights. Alice should have come back for a future episode, but not to be.
