A major reason that Greenberg is often overlooked when people talk about great ball players is that he spent many of his prime years serving the war effort and was away from baseball. This has kept his lifetime stats and therefore his notoriety down.
Another major reason this movie was so good was how it showed Greenberg's career in baseball as a Jewish baseball player. Although his abuse was less than what Jackie Robinson would later recieve, he still did suffer abuse. Also, he was watched and revered by the Jewish community. He was respected and admired as a Jewish man who was just as good as other American ball players, giving Jews a sense of pride. One of the best parts of the film is when the viewer learns that Greenberg talked to Jackie Robinson about playing in baseball as a minority, and gave him support.
Whether he was helping Detroit win the World Series, serving his country in the war, being a symbol of pride for the Jewish population, or giving Jackie Robinson advice, we can see that he meant a lot to a lot of people. This is a remarkable story about a remarkable man, through the lens of baseball. If you like baseball and baseball history, this movie is a must-see.
The movie is good enough that it seems too short. A shame that there isn't more baseball footage from that time period.
