Who am i? Why my body his changing? What i'm interesting in? This is the questions that all the teenagers are asking. Among the movies dealing with the question of teenagers and young peoples we could quote Larry Clark, Gus Van Sant or Greg Araki... but who know that Sam Remy has already directed a movie about this kind of subject?
In fact, Sam Remy his the director of the first adaptation of Spider-Man (the second and the third too) which is only the story of Peter Parker during his teen's identity crisis. Peter is trying to seduce Mary Jane, the girl of his dream, he is effrayed by the changing of his body and he is fighting against the authority of his parents (Uncle in this case), that's what we can see in the first 1'30mn of the following trailer.
So now you know that, try to remember the scene when Peter is in his room, wearing only underwear, looking at his new muscle body in the mirror and trying to spurt by his wrist this kind of white strand looking like... well you know! And when his aunt asking him what's doing, he hide himself behind the door and answer "no, nothing, it's nothing, don't worry", doesn't it look like like a first masturbation? The discovery of his sexual potential?
But don't forget one thing, with a great power comes greats responsablities!
