Steve was unlucky. His father died when Steve was 13 years old, and his mother could not cope with raising her son. Steve began to behave defiantly, violate public order, steal, fight, and he was placed in a medical correctional facility. The action takes place in Canada, where there are also such institutions as in Russia. But they kicked him out of there after 3 years, they couldn’t cope, they didn’t cure him, they didn’t correct him. When Steve set fire to a cafe, hurting other children, his mother was called and her 16-year-old child was returned to her. Mom hides an inner emptiness behind her defiant appearance and manners. She is beautiful and young for her 46 years. But she is internally lonely, she has neither education nor internal support. It relies on external supports in the form of alcohol and cigarettes. For a while, they alleviate pain and stress, but do not allow you to build real closeness with other people, to experience real joy from overcoming difficulties, from real achievements. Mom invests in her appearance; it is important for her to receive compliments. She may have narcissistic personality disorder. Mom is very sorry. She did not have enough parental resources to cope with her son's illness. It is not easy to cope with a child alone. Especially with a teenager. Especially with violations. In the film the diagnosis "ADHD" is given. If Stephen were older, his behavior would be consistent with “antisocial personality disorder” (“psychopathy” in Russian terminology). This diagnosis is only given to adults, like other “personality disorders” (narcissistic and borderline). In the meantime, he is diagnosed with ADHD. Steve has a desire for freedom, but there is no awareness of boundaries or understanding of safety. There is no awareness of the consequences of one's actions. Perhaps there are organic reasons for his disorder, but for sure there are also psychological reasons, shortcomings in his upbringing. Steve’s mother cannot cope and sends him to a psychiatric hospital. This leads to tragedy. Steve is a victim of weak women (a neighbor-teacher also appears in the film) who use him to solve their psychological problems. I feel sorry for both mom and Steve. He lacked male upbringing and positive male influence. But she lacked connection with reality and support. But “Good Will Hunting” was more fortunate. Although his backstory is no less dramatic, he is generally an orphan. But he met a talented and kind psychologist on his way... I watched these 2 films one after the other. "Good Will Hunting" gives hope. And the film "Mommy" leaves a wound on the heart in the form of a question - how to live and let others live, despite psychological and social restrictions.
