As a writer myself, I have a very critical eye to movie adaptations of novels. I was prepared to be disappointed.
Much of the allure of the novel stems from the long strings of passionate dialogue between these two unvconventional characters. I questioned the filmakers ability to convey the depth of emotion necessary.
They pulled it off for the most part. There were a few times when the audience laughed when the joke wasn't intentional and the stunt work could have used an infusion of adrenaline. Overall the movie brought forward the same integral themes and emotions from the book while staying true to the characters that Stephenie Meyer so carefully crafted.
