First off for this review you have to understand I am HUGE Kurosawa fan since well ..forever.  I love Samurai films and this one did not disappoint.  The political maneuvering to ensure the right thing was done for the Japanese people felt like something that really could have happened.
My Re-watch value is low because I rarely re-watch samurai movies unless I am sharing with my friends, but I may buy the dvd to add to my collection to make sure I always have it to share.
This is just an opinion, yours may differ.
