I've read many poor reviews for this movie based on he fact that there are significant differences between them and many believe that Howard should have stayed truer to the book. If this is your sole criteria for judging the movie, then the review is understandably poor. However, if your basis for reviewing the film is strong acting, fast paced action, great cinematography, phenomenal storyline (which may not be 100% true to the book), your review would undoubtedly be good.
