All sports movies should be underdog stories, and most are. They make the films easier to watch for those not incredibly interested in the sport. Additionally, if they’re using the sport as a backdrop for a more important issue, it’s even more poignant. (Especially racism a la Remember the Titans and Invictus.) Moneyball was a baseball movie about stats and economics. Baseball, stats, and economics are each far from exciting. The screenwriter and actors put up a valiant effort to make these subjects interesting. They didn’t quite succeed.
