I must admit, I came from video games and the Masterpiece Battle Royale. Even though those games never mentioned directly that film series, It is clear that if you have a Yakuza film, you must have been directly or indirectly inspired by Kenji Fukusakis Madness Series. I have seen the first five films, and I don't understand a thing, but I love it! Chaos, crime and Japanese Crime History lessons. If you are a fan of the Yakuza game series (like a dragon), and wanna also see what Takeshi Kitano has made a more thoughtful introspective take on that subject, get yourself the whole set and have fun! The picture and sound quality is pretty good, the extras are a banger, and the fun is Top notch! Go watch more world cinema, and watch everything you can, while you can! Have fun
