I read the book and saw the movie last night. It was very different, including the end. For those who are curious, I have put the major differences in white:
-Jesse is not an arsonist or really much of a delinquent at all
-Brian does not sleep in the firehouse
-Julia is completely cut out
-Kate has a rather dramatic suicide scene
-It is Jesse who tells that Kate put Anna up to it
-The court case is actually hardly mentioned at all, it seems like an afterthought
-Anna's personality seems very different, she does not play hockey, polish his doorknobs, etc.
-The whole service dog thing is very underdeveloped. You only hear him quip about it once.
-The huge dramatic beach scene was added.
And here's the biggest (the ending)
-KATE dies in the end and Campbell brings the verdict by after her death.
The movie was okay. They tried way too hard to make an "artsy" movie and the songs really took away from it. People were laughing at the lyrics in places that were suposed to be somber and htere were way to many montages. The movie jumped around only barely following the book and at times you couldn't tell easily if you were in the present or the past. Reading the book definitely helped because you knew what to expect, although I was rather disappointed that I geared myself up for certain things that did not happen.
The movie was okay but by no means a good movie, or even a good movie based on a book. The one thing I will give it is its unflinching look at a family in crisis and what it's like to go through an illness like that. I can't think of a single movie that has shown such a raw portrayal on screen, and it's something a lot of families may be able to identify with.
