I felt this movie was very slow moving the first 40 minutes until I thought I recognized parts of the story. Then i checked and can see it is based on the same novel. But I do find the pain and the anguish is better felt in the Japanese version .
Well for me this movie should be a skip, but it may be okay if you have not seen the other version. I cannot say if it is more true to the novel either. But anyway I do not understand people describe this as a masterpiece. I neither found the acting or the dialog very inspiring here.
