Take care not to be misguided by the other comments on this movie! The action in this movie does not amount to "good" and it hardly even qualifies as mediocre. With a bad plot and too much bad storytelling instead of action, there is very little to entertain an experienced and/or demanding observer.
Kane Kosugi is good in his movie-display of martial arts, but worthwhile action is presented only in 2 and a half minutes of the entire movie.
The other fights have choreography, the quality of a bad Van Damme movie. ("I will block your kicks with my face until your feet start bleeding!") The showdown disappoints the most. It made me wonder if the action choreographer had left the crew, by that time. Cut-scenes, in no particular order, and devoid of any tension, are supposed to excite the audience. You may be familiar with that if you have seen the showdown of "Naked Weapon".
