SPOILERY
This movie is very literally impossible to watch, start to finish. Even if you for some disconcerting reason enjoy gore and kronenbergy putridity, this is still impossible to even glance at.
It's not just that it's so ferociously revolting in concept and visual execution, it's that it is all far too excessive, prolonged, ultimately almost entirely meaningless, and renders the film's major themes secondary or even irrelevant. A totally impoverished vision of the filmmakers vomits itself onto the viewer, sadistically. Perhaps it is deemed "body horror" solely because the project has no mind, heart, or soul.
This is more appropriately a dystopian allegory of "becoming a mother" than "investing in cosmetic obsessions/aging." I don't even particularly understand how this film is supposedly representing the latter: there is a flimsy theme of "media pressure, fears of aging, and self-loathing;" yet, the storyline, dynamics, messages, tone, greater network of themes, and all of the symbolism carry the trauma narrative of Pregnancy, Birth, Motherhood, Mother-Daughter Bonds, Self-sacrifice, and Generational or Genetic Curses.
So I see The Fly + Carrie + Requiem for a Dream, with the intention more or less of Rosemary's Baby. That's what this useless, confusing, and shockingly derivative drivel essentially is... with mere allusions to the beauty industry tacked on as a means to completely misunderstand, confound, and/or ignore its own point.
It's messy and heinous with zero substance. It has a way of trivializing its own self, selling its soul for something wacky and shallow to cut in and take over. I understand that's what the film is about, but the filmmakers/film should be depicting that, not actually becoming it. The thing cannibalizes itself and its own makers horrendously and unwittingly on a world stage.
It is grotesque most of all for how it mindlessly and irresponsibly misconceives its own self.
