I walked into the theater
hoping they changed PC in the movie, because I finished reading the book and MAN! I thought it dragged so badly. I especially hoped they would cut the time spent travelling through the forest to get to the How; they did (YES!). All kinds of other things... I'm just glad they made the movie what it is.
Sometimes books
need to be changed. They should make "The Scarlet Letter" into another movie. Yeah, they've made like 9 scarlet letters before, but I read the book. Talk about boredem! The emotions of the people play a big part. They could really make a good one if they expound on the music (
has to be a good score, or it'll fall flat). The camera angles have to have a certain way of treating the characters on screen. The color tint, the acting, even the lines! Sure, change the book a bit, but a movie isn't going to be good if it has no cinematic artistry. "Braveheart" was wonderful, but is radically different from the real history surrounding William Wallace.
"Prince Caspian" was a good movie because it did away with many of the unneeded lines and descriptions. "Lord of the Rings" would have been terribly dragging if it followed the books verbatim. Changing the book is sometimes necessary, because the book, if directly copied, would look rather lame to a viewer (just think if they included Aslan at the end...
prancing with Bachus! nnooo!!). Think of the people who didn't read Prince Caspian. Reading is different than watching, and PC was done marvelously IMO. Much more mature than the first, and captivating cinematically as well.
And if this particular series does not continue, they'll never be able to do it again, because everyone knows the actors, and the actors grow up.
