I feel this movie did the book justice but it went through the events of the book very fast. Perhaps it would’ve been better if they’d split the book into 2 movies after all. While the book was also fast, especially part 3, the movie basically skips through the book, smooshing whole chapters into one scene. It also cuts various characters out completely, while diminishing the importance of others. At least they don’t have to worry about succeeding enough to produce a sequel, as this isn't a prequel series.
