They play the roles of a stereotyped couple because the man is insensitive and the woman is dedicated, but undervalued.
Explanation:
"Kramer versus kramer" is a film about a dissatisfied couple, where Ted Kramer is an insensitive man who does not care about his family and who only cares about work. His wife, Joanna, is very dedicated to her family, but she feels devalued and decides to divorce. This is a very stereotyped role for both characters, as it is a common thought in society, sees women housewives as dedicated and devalued and men focused on work, moreover, these are roles that have been repeated in many stories.
