I have watched this TV serise since last month , intermiitedly, last long for one month until Dec.
This series described a babyboy's grown-up story with his mother, she is too close to her son to generate an abormal relationship, thereby cause a bad consequnce.
The boy is kept in house withou any activities like other child, he felt depressed and even desperate to his mother, so he will chage another person's identify to do something unexpected like killing people, so called black cut in the TV. The mother always regard his son as a babyboy even though he is 18 years old, the age which can go out to date, actually there always a lot reasons to stop Norman to do what he likes.
The mother is over-react to son's thoughts and ideal , over protect her son's from normal activities and situation. This TV series shows an education problem in each family all over the world, mother's particular possessive, Son's timid and anbormal.
From my view,a good relationship should comfortable for both sides, as a mother, give a moderate education and careness is enough, a child should shape his own identification during the grow-up period , whatever , good or bad.
