Alejandro Gonzalez Inarritu made a well-deserved leap into the renown film-making pool with Amores Perros, and his follow up 21 Grams shows him with plenty of talent to spare. He also gets three (or more, depends on how effective one thinks the supporting performance were) forceful, compelling performances out of Sean Penn, Benicio Del-Torro, and Naomi Watts. They're involved in three interlocking stories- Penn as a mathematician with a rottening health and a near-rottening relationship; Del-Torro's found Jesus Christ after being in and out of jail for part of his life; Watts is a house-wife who may have some deep troubles within her mind. Each of the three leads doesn't go for cheap drama, and each one plunges the depths of their own abilities to find truths that might not be possible with lesser material or a lesser director. I won't say much more about the stories, however I do have something to say about the structure of the film. The script brings some mesmerizing scenes, ones with great tragedy that bring out a viewer's compassion.
Never-the-less, there was something about the structure that I didn't think was all that great. In films like Once Upon a Time in America, Reservoir Dogs, and even Memento, the scrambled story structure had a purpose, adding appropriate twists and turns for the audience. 21 Grams (like Amores Perros in a sense) has that non-linear basis to it too, and sometimes it works for the audience to react. But I think there would be a lot more power to how these characters' fates and tragedies unfold if it was told linearly from start to finish. In many moments in the film I found myself knowing a little too much before a particular scene unfolded, or I found myself guessing about something that I didn't need to (one of the points of non-linear storytelling is answers first, questions later). It wasn't an aspect that made the film bad, yet the stock that writer Guillermo Arriaga and director Inarritu put into this structure over interlocking the stories in order, or perhaps telling each story separately, is the film's only drawback.
