Sean, Benicio, and Naomi turn in Oscar deserving performances in a screenplay that reveals itself little by little in a scrambled fashion. This film's disdain for chronological storytelling makes it all the more compelling and in fact brilliant! I know of people that saw the film who had no clue what happened but I was moved by the unorthodox screenplay and entranced throughout. Do we lose 21 grams of mass at the moment of death and is that 21 grams our soul? Does our soul continue on? I can't know, who can know, but it's intriguing to theorize and discuss. I rather like the idea that our souls do survive then inhabit some other life form (reincarnate souls is a comforting thought), but I've been knocked cold for a prolonged period of time and I can tell you from that experience the only thing I experienced was no experience at all! However I've had other experiences that convince me malevolent other world forces are at work which suggests there is other worldly good forces as well. God and Satan as an antagonist duality or one in the same? Don't the Freemasons believe God and Satan are one? By the way this is an amazing film!
