[Editor’s note: The following article contains spoilers for “Barbie.”] A doll that dismantles the patriarchy? Now that’s worth toying with. Greta Gerwig’s smash hit “Barbie” plays — at times — like a meta commercial for the many products (Barbies, Kens, Skippers, oh my) the Mattel toy conglomerate designs, builds, and sells. But at its heart, “Barbie” is a strong feminist statement against the often pathetic ironies of patriarchal rule — even though Mattel brass might tell you otherwise. The toy conglomerate, which produced this highly original movie, noticeably shied away from publicizing the film’s feminist messaging in much of the early looks at the film, including a “2001: A Space Odyssey” parody teaser.
