It is a very good movie. It has a nice plot, good pace, and good acting. It also nicely and extensively pictures the Japanese culture. Although I am too far from any knowledge of Japanese culture to judge if it was at all accurate. Specifically, I have my doubts about Sean Connery‘s Japanese, since his Russian was terrible. But who am I to judge? :)
Anyway, I’d give it a solid 7 out of 10. Good entertainment.
