There is not much more that I can add to Michael Stephens' review. As the film closed, I, too, had tears running down my face in awe of what had transpired, not only because of the greatness of this film, but the courage and loyalty of the men and women depicted in this magnificent story.
I am a Caucasian American, but I have a deep love for Asian culture, especially the Japanese culture, so I have a little insight to their way of thinking. I agree with Michael that many Americans will not be able to completely identify with certain events in the film. Nevertheless, you must have a heart of stone if you cannot feel SOMETHING for what happens in the film.
Yes, this is a long movie, but I found I wanted more. The story, the acting, directing, EVERYTHING was MAGNIFICENT!!! And, of course, there was TOSHIRO MIFUNE, brilliant as always even in this limited role. If you are a fan of Japanese cinema, you will see MANY familiar faces. And, to top it off, the music was composed by the GREAT Akira Ifukube.
My only complaint is the DVD. As beautiful as this print is, it still looks like it needs to be restored. I can't imagine how wonderful that would look!! Also, some extras like a short background story would be helpful to those that have no real knowledge of Japanese history. I CANNOT recommend this film enough!!
