I know the rules of baseball (better than American football) but, since I'm European, I'm not really familiar with this sport but it didn't really matter since this movie was dealing with the business side and the story line could have been applied to many other sports. Indeed, they developed here a very interesting theory that sports managers overpay their stars and neglect underrated players who could play for less than half the same price almost at the same level. So, in Oakland, they bought some undervalued players solely based on their statistics. Unfortunately, they spent only 5 minutes actually explaining how it all worked and I wish they did spend more time to explain the whole thing. Honestly, after that, it followed the usual pattern of any sport movie (they kept losing and losing and suddenly they kept winning and winning...). Something surprising was that the great Philip Seymour Hoffman showed up in a very thankless role. As usual, he completely disappeared behind his character but he had almost nothing to do during the whole thing except grumbling against this new strategy. Even worse, Robin Wright showed up in only 1 scene which was nothing mindblowing whatsoever. Then you had Jonah Hill who gave a very nice performance but I wish they developed his character a little bit more. I mean, he was a geek who could manage statistics pretty well but, aside from that, you learned nothing about him. What was left was Brad Pitt who basically carried the movie on his shoulders and he did it very well. Indeed, there were so many layers with his character, it was just fascinating to watch. This visionary manager who couldn't stand to loose (the reason why he probably didn't make it as a player) was definitely one of the most convincing performances by Pitt. To conclude, it was a very interesting and entertaining sport flick which showed a different side of this world, and, even though I wasn't completely blown away, I really enjoyed it and it is definitely worth a look.
