I was only vaguely familiar with the premise so went into it with no preconceptions of the outcome and I really enjoyed this one! Jessica Chastain and Idris Elba are great. They absolutely command your attention when on the screen.
The story unfolds well and deliberately (how very Aaron Sorkin). Sorkin's directing debut was good, not mind-blowing but good. Pretty standard act/react back and forth with one or two cool shots mixed in.
