This was classic Hollywood/Disney, and I do not mean this as a compliment! Instead of saying this is based on C.S. Lewis' work, it should state LOOSELY based on it. They diverted off the story line to add excitement in places where the story is exciting enough. As a stand alone movie, not based on any other work, it's filled with adventure, fantasy and fighting, and is quite entertaining. This is my biggest beef about books made into movies: They just can't seem to follow the story! For once I just wish when a filmmaker made a film from a book, especially such an excellent book, they would do their best to follow it! But all you have to do is look at other books made into movies to see that true adaptations are hard to find. The Little Princess (Shirley Temple) brought the father "back" to life (What?? He died! Deal with it! ) and Janette Oke's Love Comes Softly series only kept some of the names, but hardly any of the story line! If you aren't going to follow the book at all, why not make movies without using a book? Write your own story. But I guess whoever is responsible for the story line is not that imaginative. Or ambitious. Sad.
