The movie did not live up to the book. It highlighted certain stories, left some important information out and then added some parts that possibly contributed to appealing to mass audiences, but took away from Liz's true story. I thought the bit about Felipe being the one to run her off the road when she was on her bicycle was unnecessary and put a negative light on his character.
It would have been nice to learn more about her battle with depression in the film, thereby not making her seem SO incredibly self-centered in the movie.
