I thought I would really like this movie, but of course, considering the stars, I didn't. It actually broke my heart. Although it supported women, it hated on men. Here's your *spoiler alert.*
The movie is more or less a fight between matriarchy and patriarchy, and rather than seeing both as wrong, the movie celebrates matriarchy and hates patriarchy, and while you expect and hope throughout the movie that it will end in a balance, it never really does. In the end, the Barbies just tell the Kens that they need to figure out who they are on their own without them, but then they're not allowed to have positions in government, and one begs to have representation on the supreme court, to which the female president says he can have a position in a lower court, and then the Kens celebrate as if that is a fair victory. It's implied that the Kens are homeless, and the Barbies purposely manipulate the Kens who are in love with them into thinking they like them back, only to break their hearts and take away their voting rights, which is celebrated as making everything right again in Barbie Land.
Context: The Barbies oppressed the Kens, so the Kens, understandably, in their anger take over Barbie Land when they see that men can be seen and recognized and do important things in the real world, creating a patriarchy, and rather than finding a balance in the end where no one is oppressed, the Barbies just oppress the Kens again, and the matriarchy is celebrated. Its a revenge story, and revenge isn't going to fix anything about our world.
