I've seen the movie twice now, and it was most certainly worth it. They stayed very true to the book, yes there were a few added scenes and a few things that got shortened up, but those things never changed the story in any way. In fact, if anything, the added scenes made the movie better. The acting was all around very good. The parts of Edmund and the White Witch were perfectly cast, both leaving you with the right emotions towards the character. I would recomend this movie to any person of any age (and that's something that I would rarely do, I'm usually stuck saying that a movie is either for just adults or just kids) and I think that anyone who has read the book will especially like the movie.
