This movie starts off really really good

First we find out that our main character is at the end of his rope. By chance he stumbles onto a big bust that becomes his goal. But the real tone setting scene is the part where Sato comes into the bar where at the time there is a meeting between the Yakuza and Italian mob. What I love so much about this part is in the way Sato reacts to the Japanese insult. Sato really executed the guy in front of everyone, thereby setting the tone for the rest of the movie, and that tone is this: you can't mess with Sato, if you do you better know he is capable of taking your life. And so that is one of the reasons why this movie turned out so great.
