Wow! Let me say that again to emphasize my first thought when the movie was over: Wow!
I was amazed how incredibly well the two principal actors manage to give the main characters such depth and nuance without words, using only looks and other bodily expressions to communicate with each other. Moreover, the magnificent photography and almost hypnotizing quality of the movie reminded me of The Return, a movie for which I have similar feelings; in fact, what I wrote in the last paragraph of my review of that film also applies to 3-Iron.
3-Iron is not a mere movie but an unforgettable movie experience; it is a cinematic masterpiece and a fantastic work of art.
