I have seen this movie 3 times now and have cried every time. Usually I like the book better than the movie, but I enjoyed the movie much more. Its not true to the book, there are a few moments that they leave out, but overall a powerful and touching movie!
Enjoy it!
The movie was wonderful. Funny you mention the book: I tried to read the book but for some reason I just couldn't get into it. However, I loved the movie. Maybe now I'll go back and try the book again..
