"Hidden Figures" is the (mostly) true story of a bunch of human calculators who worked for NASA before the first IBM computer was purchased (and learned to program it afterward). Being mostly African-American, they were kept out-of-the-limelight, and endured second-class facilities and treatment while being relied upon for some of the most critical calculations in putting a man in orbit and bringing him home safely.
It was inspiring and heartwarming and thrilling and very well done. I think the actual math involved was considerably underplayed (I mean, even I could almost follow it!) but the personalities were fascinating and, in the end, redeeming.
