If you have read the Caspian book, don't expect the movie to be like the book. Enjoy the movie for what it is, a good movie. If you have not read the book, you can still enjoy the movie for what it is, just don't assume it's like the book. I think reading the book series (seven books, of which Caspian is the fourth) is a great thing to do, keeping in mind it is more geared towards children. If I had children, I would take them to see Narnia’s Prince Caspian.
