This is now become one of my favorite movies of all time. It explores the idea that there are natural forces at work in the physical world, but also spiritual forces that are entangled with the physical world. The relationship between Isaac and Clara is central to this movie Because they both move closer to each other's Point of view. They were like an equal balance of physical and spiritual. And that they both are at work in our worlds. I recommend this movie to anyone at any age.
