Meh...I know people rage over the differences between the books and movies. Can't detach themselves and realize that every cinema adaptation makes changes that translate better for cinema. No you don't need to change characters or personalities. Which they did. But some of the storyline peaks or including other visuals to heighten the feeling the audience is supposed to feel are essential.

Movies are supposed to flow like movies and books are supposed to read like books. But when a movie flows like a book or book reads like a movie it never works. The movie becomes slow and boring and the book becomes a convoluted mess that you can't keep track of.
