I just reviewed the book, I read it first only this year and had wanted to see the film for a while and actually just watched it the other week.
Once the film ended, I sat back and in the silence that followed between myself and my partner I whispered one word that describes this film entirely...'amazing.'
You have not lived until you have seen this film and read the book, I was leaning forward in my seat at the climax with wide eyes filled with tears. It was the most powerful moving film I had ever seen in my life.
