To start off, The Celestine Prophecy is one of my favorite books. I've read it more times than I can count. By shear coincidence, I happened to find out it has been made into a movie and is playing at a theater in Port Chester, NY. So John and I made the drive out there today to see it. It was really good. I was amazed that it translated so well into a movie. Although parts were poorly done or cheesy, all in all, it was good. If you've read the book, I recommend seeing the movie.
