She's everything. He's just Ken.

Barbie and Ken are having the time of their lives in the colorful and seemingly perfect world of Barbie Land. However, when they get a chance to go to the real world, they soon discover the joys and perils of living among humans.
In Barbie, consciousness is carried by toys and objects — a plane of “doll society”. The story fights on E8/E9/E10 of the E0–E14 reality ladder, compressing gender, identity, prejudice, patriarchy, consumerism.
Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
Other films that move a human interior onto the same kind of thing.
