21 Grams, gonna watch it!
What is the movie's message? That people shouldn't be so quick to judge others? That could be one interpretation, but what's nice about the film is that it doesn't hammer this lesson into us. It just tells a moving and stirring tale about complex characters, and viewers can take from it what they please. The title refers to a parapsychological belief about the weight of the human soul, and it's used in this film as a metaphor for the fragility of life. If life is fragile, then it's also precious, and people need not waste their time on vengeance.-extract of a review from imdb
