All i knew about the film was what i had gathered from the trailer, and that it was based on a book.
Now.. Right up till the very last 10 minutes of the film i did not suspect anything of the film ending as a tragedy. I wont say any more in case anyone is going to see the film, sorry if i have already ruined it for you. But never the less i still recommend you go and see this moving film.
But keep in mind, too many tragedies in a short amount of time will most likely make you a very melancholy person.
So BEWARE: People don't like being around sad people.
