There is no motivation to the protagonist in the movie at all. There is nothing in this movie to be rated high except for the acting which is very good. At least it can be directed as if father realizes his mistakes and send his son to pursue his passion to become a writer. The story can be written better than this.
Audience will only think about the parental abuse but not about the interests of the children. Movie highlights more on abuse which is not a good motivation to viewers of below teenage.
