This movie works for families interested in movies depicting traditional family values because Ossie Davis and Ruby Dee, as the grandparents, show so much love for each other, their orphaned grandson, and others. Young Jason has a double role - on one hand he is the catalyst that helps their grandson get past his grieving; on the other, he reminds Mack of an incident predicated on racism but in reality was just plain bullying.
[It also helped (for me, as a childhood fan of the 1950's Chicago cubs) that the great Ernie Banks was Mack's old friend. All the boys on our old Little League team dreamed of playing baseball like Mr. Banks!]
This is a wonderful family movie about baseball, boys, facing the past, sticking with one's "gut feeling" and learning the facts, consideration (and the lack of it for some) for other people's feelings, history of racism and for learning some baseball history. If you have Little League age boys or girls, you can safely watch this movie without fear of violating any traditional family values.
