You must understand that violence in a movie is only a tool. If it's used badly, it will be horrible. If it's used correctly, it can be very interesting. But, essentially, it's just a tool.
Nicolas Winding RefnThe Oriental approach to violence is a much more aesthetic and poetic approach, whereas in the western world, violence is put in because you can't solve the problem. Violence is always the last solution, but unfortunately, in cinema, it's the first solution, because it's easy. And it's often too easy.
