This could've been one of the best adaptations of a book. The casting was perfect, the acting fantastic. They even cut out the right parts of the book to fit this original story into a movie. BUT WHY CHANGE THE ENDING?! The ending is the ESSENCE of the book and is what makes it ORIGINAL and DIFFERENT to every other 'cancer themed' story. Total Hollywood copout and ruined the whole movie. Absolutely gutted and immensely disappointed.
