Could have been so much better

Excellent idea for a film, including a great twist in the final frame. But overall I found it very disappointing. It looked as though it had been savagely edited to bring it down to 105 minutes. Unfortunately what remained included far too much of the tedious back story of Matt Damon's character, presumably because he was very expensive. Damon and Jude Law both went through the motions, perhaps because of slack direction. Only Kate Winslet put in a performance worthy of note. Apparently this film has made a good profit, so my reservations count for little.
