Usually, I'm always up for gangster movies. It does not matter from which country the film is from.
The IMDb's synopsis is quite misleading. Xiong doesn't get released from prison when a rival gang wants the turf owned by the gang Xiong integrates. Those two facts are not connected.
Xiong is loyal, and the first half of the movie tries to imprint this in our minds. But the movie's plot seems to focus on both Xiong and Qing-Feng, which is weird. Xiong is not participating in most of the action, but Qing-Feng appears to be the main focus of all this drama.
About the acting, nothing out of Taiwan's expected ordinary. No one really stands out.
Finally, I have to say that the movie's plot is alright, but you see that it is more about the drama than anything else. Quite a few action scenes happen, and they are brief.
I probably would only recommend this film to someone who would tell me that he likes gangster or mob films. If, by then, I could remember this movie's title.
