If you read (or audibled) the book, do not see this movie. It will disappoint from every measure.
If, on the otherhand, you have not read or listened to this book, there really is no reason to see the movie.
Therefore, the only people you should see walking out of this movie are people who have nothing at all intelligent to do with $20, or very sad and disappointed people wishing they still had $20 in their pocket.
