Well it's not a good film to watch on Sunday with your family. It's not a good movie if you're looking for some action. It's not a good movie if you're looking for philosophical dialogs.
But it's a great movie if' you're a Kitano fan. It's a great movie if you're interested in Japanese culture. It's a great movie if you like to sit back for a while and think deeper about what you're watching - it seems that throughout the film there's not much going on - the main character remains mute for most of the time, there is no music soundtrack in the background, the plot itself is not a straightforward one - you'll get the point right only after the last scene.
In some moments "Jugatsu" seems to be telling a simple and seemingly a little boring story - but a second after it blows in your face with aggression so intense that you start to think were it came from. It is not about blowing guts out or shooting people in the head. It's deeper.
What "Jugatsu" is about ? It's about revenge, loyalty, love and violence.
