"You have created your problems, just you can solve them"

This movie is full of poetic "catchphrases", but maybe none of them summarize it so well as this one above. We wait the protagonist solve the problems that he had created by himself, but it looks he just make them worse in each minute.
In the beginning of the movie, the first-person narration and the zoom in the protagonist's face show us that the movie will be seeing under his vision, thus this movie will show a history under the vision of a asshole, paranoid, depressive and poetical guy, in such a way that watch it is almost like if Fernando Pessoa had made an erotic work or something like that...
As a consequence of that, we can notice that the others character have a very weak personality, because, as the protagonist have said, he just think about himself. In any moment of the movie it's developed some layer about Julia, Carol or the father of Zeca, they are summarized in an unique personality, because it's how Zeca see them.
I felt the movie tries to create a Dom Casmurro vibe, but (as Dom Casmurro) everybody knows that everything it's just a paranoia of the protagonist and Capitu/Julia doesn't betrayed him.
