So-so plot. The story feels disjointed with quite a number things left unexplained (like how did Hahou Mo become instructor in the first place? Why don't the cops try to secure the suspected victims? Why did Sinn Ying do that in the last half of the movie?). But I suppose plot is not meant to be the strongest department in this movie.

It's the action. You'll see some names from previous Donnie Yen's movies (Ip Man), and they're all great martial artists. The fights, which involve the five phases of kung fu, were all done nicely. Especially the ultimate fight between Hahou Mo (Donnie Yen) and Fung Yu-sau (Wang Baoqiang) which takes place in the middle of the street - with cars and trucks passing over! The choreography is stunning and the camera movement is swift, capturing all essential shots needed to portray the dynamics of the fight.
