Sindrom Sindroame

In quality of a son being in a farway relation with it's father i can tell this movie gives a profound and mystic emotion over all the lack of love that a man can experience in his journey to maturity, growing alone. The impersonation of Brad Pit that has a perfect control of it's own by rythm and pulse it's like he was preparing and contemplating all of his life about this act is truly majestic. The dimension that it gives in the final act when the father ascks to be let'n go and the act of leting it go from the perspective of the son is absolutley the drama of the atachement that we all feel for our own parents. The rage that Brad Pit has in the end is something that can't be explained it only can be felt. I am wondering how did the manager of this film know this facts so close was he also growing alone inside?
