Variety's chief film critic Peter Debruge has nailed a detailed review of this film spot on. If you think a story about three talented, capable, strong and determined African-American women and the race to put Americans in space and on the moon is some sort of fantasy, then read his review and better yet go see the movie.
It is a wonderful film, suitable for all ages and makes me proud to be an American. Not proud of race relations in the last century, but proud that an overwhelming majority of Americans overcame prejudice and recognized the talents of people whose skin color was different from ours.
In these, the early years of the 21st Century we still have a long road to travel to truly be "one nation under God," but the story of these three women should help us travel that road.
