Another MovieBuff’s review published on Letterboxd :
An out an out action movie which keeps you connected cause of the innovative action sequences. For this genre it's rare to see movies without trademark Chinese acting. Yuen Woo-ping who then went on to direct action for many Hollywood movies.
The backdrop of Sino-Japanese war adds a few more emotions to the otherwise plain action.
Mind well though, the movie is a treat to lovers of martial arts action only. Nothing insightful other that that.
