I didn't read the book before I watched the movie and I saw lot's of people on Facebook saying they had questions after they watched the movie but those who read the book said that not everything from the book could've been included into the movie. I've started reading the book and I'm only two chapters in and can see that this is true. I loved the movie but I'm already loving the book more. So judging by those who gave this movie scathing review, I'd say they didn't read the book and if they did and still didn't get the movie, that's sad on their part. If they didn't read the book, give that a try. I bet it'll change their perspective.
