A film that reflects reality. Even though the treatment of mental disorders has improved significantly, they still face their own past and social exclusion. If they can not get out, they will inevitably be forced back to the corner. In the first two-thirds of the movie, the perspective is limited to father and son. When the relationship between father and son improves, the former fiancee suddenly throws the protagonist back to hell, and the neighbor's exclusion brings the tone of the whole movie back to the tragedy of realism. This arrangement undoubtedly highlights the conflict of the drama, but the contrast is too large, which actually harms the plot.
