content: I could rate this ten stars! Everyone in the reviews above has divulged their version of "the heart of" this movie and the motivation behind the scientist's and James' actions. Yet I can only tell you that it is a movie that you can relate to, and mysterious at the same time. If you like to be curious, buy it and watch it every once in a while - leave enough time for yourself to change a little. Each time you watch it, it will poses another intellectual, yet enjoyable, challenge.
