This movie is, at least, morally baffling. Wagner is a veteran killer, who takes his work very seriously. However, he's dying and has no one to pass on his legacy of death. He decides, therefore, that it is best to take the young Max for his apprentice.
Mathieu Kassovitz is in great shape in this film. In addition to ensuring a solid direction, he also makes one of the main characters, namely Max. Nothing to point out from negative. The actor was able to give the character a look of ingenuity and inexperience that fit well with the situation and with Wagner, a more cunning and sinister character, who was well interpreted by veteran Michell Seraut.
Forget any notion of ethics and morals. The film is very amoral and does not mind trampling our most elementary concepts of society. It tries to point out blame for the clumsiness of our society, the inherent rot of humanity, bad television entertainment and the influence of mass communication. This is something that leaves us totally out of our comfort zone, coupled with the virtual absence of female characters and ultimately a bit disconcerting.
I personally enjoyed this movie, although it is not an easy movie for everyone. There are many artistic elements here, and I particularly liked some camera angles and shooting effects. But it lacks a solid moral background that allows people to like the film more.
