The heroes in ‘Kick-Ass’ are not made of special forms of matter and are not un-breakable. They try however to live to the ambitions of the super-heroes myth in a world which seems to believe in myths, and take the superhero life-style paths. Of course, when regular people act as super-heroes they can also get hurt, especially as they are at different levels of evolution in their training. A dad and his 11 years daughter seem to be the most advanced, with a high-school teenager who is actually the main hero following them bravely on the same path. Another teenager rather seems to be on the dark side, but he also tries the funny costumes and the weapons of the trade. The names of the heroes are Big Daddy, Hit Girl, Kick-Ass which seem like warnings not to take things too much seriously. There are some background explanations, but these do not count too much. The general tone of the film is on the comic register, a combination of superheroes parody and teenager growing pains comedy but the mix becomes lethal when it comes to action scenes. These are actually as violent as you can get in a Tarantino movie, and the scenes featuring the father training his 11 years daughter to become a killing machine (even if for the good cause of justice) risk to upset anybody who stops for a second to reflect at what is presented on the screen, and takes the subject too seriously and out of the nonsense territory.

The film does also belong to another genre – the ‘how could Nicholas Cage pick such a role?’ one. With all due respect for the film, which is actually a well made, well paced and entertaining movie if you can overcome or you do not care about the moral aspects, Cage’s presence in a supporting role in which he walks most of the time with a ridiculous thick make-up is wasted time for his enormous talent. That’s certainly just a (big) fan opinion. Otherwise you can accept the convention and just enjoy the wild ride.
