I wont write about the plot, as there is already a review which comments on that.
What I love about the movie is the chemistry between Brad Pitt and Claire Forlani. There are times when they are just staring into each other, Brad Pitt carrying the expressions of a puzzled child. The soundtrack is great, and the haunting piano playing in the background is too good to forget.
Yea, there have been a lot of reviews saying the movie drags a lot, it could have been trimmed by half an hour... but I believe that it is these elegant moments in the movie that lend it a lot of character and grace.
A great movie if you are in an introspective/romantic mood, and want to have relaxed moments to yourself or cuddled up with your loved one.
