The movie Mio fratello è figlio unico offers a particular interpretation amid the countless films that deal with what we are able to define an era - i.e. the years of the youth protest. We try to analyze the generation of "ordinary" young people who, through a confused bind between the public and private dimension, invested at first valuable resources to pursue "another" political faith that, after a series of events and almost like an imposed choice, they no longer wanted to follow. The root of this analysis will be the progressive recall of the vicissitudes of Accio Benassi, the main character of this movie.
