People reviewing this movie poorly have missed the point. There is an ending and it is supposed to shock you into realising that this is the way the world actually is for women and how sad it is that this is reality.
I too wondered if they couldn't have made the feminine qualities dominant and masculine submissive but on further reflection, I think the way it was done was just right.
By flipping the gender roles so purely it is a great demonstration of how women live in this society.
I love, love, love the way Women's bodies are shot by the camera, just structurally without any sexualisation, this was very clever!
The film seems silly and fun on the surface but it relays a great message.
After watching this film with my (very straight, very white) father he came to the conclusion that maybe he had been underestimating how hard it is for women in our society (a big deal).
Please share this film with the men in your life and enjoy the sweet feeling of being understood.
