Imagine a free independent adult female human being. Now imagine that person being boxed as a doll and objectified by both girls playing with it, and men and women normalizing the objectification through years and years by attributing it to healthy gender norms and person-orianted upbringing.
Now, let's say that this doll somehow left the box world, not necessarily to escape, but simply to visit her objectifiers (to her, fans and creators), to essentially fix her. This movie explored the process by which an innocent Barbie wanted to meet her creators to help her, only to discover an ever deeper problem. However, unlike other characters like Pinocchio or the ones in Toy Story that got in touch with the real world, she was meant to be a real dependent person who needed nurturing. What was received as nurturing by kids was in a way objectifying, but it was welcomed unconditionally. The longing she had to change things was initiated in the box world before even getting a taste of reality. It ultimately came from within her as part of a seemingly canonical tale that was never told.
What makes this movie narrative unique and relatable is the fact that Barbie could freely choose to go back to the box, she just have to acknowledge that this newly discovered heroine origin story can steal away an established genuine identity.
