Arbitrage

I'm not sure what I think about Arbitrage. It is a tight, tense film about a billionaire businessman who is undergoing a financial and personal crisis. For the most part the story is very well told, very focused. Suspenseful, engaging. But in the end I was a little confused about what had happened, and I felt sort of let down. Also, I hated the character of his daughter and thought the tension there was contrived.
