Not very good. I don't know how you convey in a movie the daily grind of Jackie Robinson's summer of 1947, when he broke baseball's color line and helped the Brooklyn Dodgers win the pennant in the National League. This movie's attempt involves the depiction of a series of "incidents" that alternately toy with melodrama or get into bed with it. And Jackie Robinson, with his wife and Branck Rickey tutoring him, prevails!
When Robinson once or twice is shown popping out, you understand the movie-makers sensed danger. There was a lot to sense, and they needed a better remedy.
