I have a theory, which is as follows: if my reasonably beloved Rangers were not in the chase for the World Series once again, I would have found Moneyball to be at least a little less compelling than I did. Still, I like baseball in general enough to have enjoyed it in any case. It combines several worthy sports film ingredients: the rise of the underdog, impressive success, an uncertain ultimate outcome, and the thing where it is really a lot more about the characters than the sport.
Also, Brad Pitt: is there a more affable actor in all of Hollywood? Anyway, though, the premise of the book on which the movie is based is how statistical analysis has started to change the way baseball works. If you like statistics a lot, you will adore this movie. If you do not give a crap or even hate math? It still works pretty okay on the straight sports formula version. If you just hate baseball, I reckon you already were going to give it a miss, and that would probably be a good idea. Even if you find Pitt eminently affable.
