Wow!!! It's incredible to imagine that these type of film has ever been made in cinema. This is just a masterpiece overall that i can say which inarritu had made. 21 grams is not only a film about losing 21 grams during death but also carries all types of human universal emotions. All characters of this film are unimaginable. They did their part excellently. And the way inarritu had explained the story its incredible!!! I strongly recommend to watch this movie as still its rare to watch these type of movie in today's generation.
