This movie is nothing for persons under the age of 18!! It is really controversial with many bloody and brutal scenes. There are mass killings and scenes of sexual abuse. The story is quite interesting and really dark... It is mainly an action movie which is set deep in the mafia scene of Japan. Both protagonists have a hard life which will become even harder depending on their growing involvement with the Yakuza... The final scene is totally crazy and adds a new genre (for the movie). I am really excited if the second part will continue this strange change of the protagonists abilities... :) If you are a fan of brutal action movies, with gore content and a dark-crime atmosphere combinated with sexual scenes you shall consider watching it. Everyone else shouldn't even think about watching it!!
