Mother + Father: How can forcing stereotypical gender roles on an audience be a good thing?

Most people don't want to see the truth about themselves. Especially if what is supposedly true for every man or woman, is not necessarily real for them.
Candice Brietz's Mother + Father depicts famous actors and actresses...well, acting. They play the "typical" men and women. Yet through these fictional characters, there is always a bit of truth. The mothers seem extra emotional and prone to admitting they were wrong. The fathers act as the provider and stress education and discipline. Though the original context in each movie may have been to show the differences in parenting between mother and father, this piece seemed to make it easier to pick out the parallels.
Both genders are part of the larger humanity and want people to care about them, but ultimately want what is best for the child. Both are selfish and compassionate, reserved and angry. By utilizing comparisons of extreme gender stereotypes, Mother + Father isolates the raw emotion of woman and man and helps the opposite sex to understand and relate to the other.
