It's a good movie with a tragic story, with lots of emotion involved.  Reminds me of one of Shakespeare's tragic stories.

Three man with different personalities and different vision, Pang(Jet) has a vision for a better China, better living for the poor, Zhao(Andy) just want to take care of his brotherhood and family while Jiang(Takeshi) is a firm believer in the blood oath they took, he also act as the buffer between Pang and Zhao when conflict arise.

Emotions and acting in this movie is top notch alright, all three are great in expressing their emotion.

Btw, those expecting lots of kungfu fighting and action shouldn't go watch this movie, as this is more of a tragic drama story of three blood oath brothers, having different personalities and vision and having conflicts and misunderstanding because of that.
