Query: An Electrifying Journey Through the Depths of a Person's Soul!

This movie was quite possibly the best movie of 2003. No offense to "The Lord of the Rings" fans, but I was very impressed with the originality of the screenplay, the emotion coming from all of the actors, and the unique direction.First of all, the movie is about the lives of three people who all have major problems. Note: This synopsis will be very vague because I don't want to give anything away. The three people end up colliding at the end. It's so hard to explain without giving away the whole story. Let me just say this. Rent "21 Grams." The performances from Naomi Watts, Sean Penn, and Benico del Toro are all spellbinding, especially Naomi Watts who, in my opinion, should have won the Academy Award for Best Actress. Rent it and be entranced by this movie that reaches to the core of your soul and doesn't let go.
