47 Ronin is a very lean film. There's nothing present here beyond what is absolutely necessary. However, it isn't hollow or sparse like many current efforts. I will still joyfully admit that I brought a lot into it myself, and that it is very much OF myself. I cannot begin to guarantee that Keanu will wring emotion out of you the way he does for me. However, if you can recognize the appropriateness of the spartan execution, given the subject matter, and are willing to look into yourself as experiencing it, you may find similar fulfillment.
It certainly doesn't hurt that it links who I consider to be the greatest in the East and the West via the impeccable Deai Masayuki.
