Query: Very good, but not as good as the book

This movie can stand on its own, but the book on which it is based is much better. In fact, I highly recommend that you read the book before seeing the movie. Of necessity, the movie makers have left out much of the detail that led up to the action shown. It is an exciting movie, but I wish that a mini-series had been made to fully explore the content of the book.
