I'm going to have to disagree with the comments regarding Babel. While Children of Men is a great technical achievement, no doubt about it, I believe in its own way, so is the Irritu film (it won the Technical Grand Prize at Cannes last year and has received various other mentions in formal categories). I plan on watching the film again next week (it's still playing in theaters here even though the DVD came out about a month ago), but compared to his earlier efforts, especially Amores Perros, I didn't think that the camerawork drew as much attention to itself.
