Very good Japanese gangster movie.
It has a classic story of struggles between organized crime families and a hero falling in love with a beautiful girl resulting in becoming his only weakness. It has a few classic plot twists that world rather well.
The acting is good in general, yet I still have a hard time finding the reason behind the hype of Jared Leto. The stereotypical Japanese stoic manner is well portrayed.
The movie is absolutely enjoyable and recommendable if you are into stories about the yakuza or similar organized crime.
