Textured with Williams’ usual grain and kept alive by his keen eye for detail, “The Sweet East” essentially sees America as a series of concentric cults. Lillian is like a teenage Virgil leading us on a tour through some kind of stupid new hell where anyone who believes in anything does so with an all-defining religiosity that demands to be mocked.

Everyone sees her as the perfect screen on which to project their own narrow view of the world. That’s true of the self-obsessed filmmakers who “discover” Lillian on the street (they’re played by Ayo Edebiri and Jeremy O. Harris, both very funny as hyper-talkative artists who assume that everyone sees the genius of their inane period piece). It’s true of the hunky movie star who turns her into the paparazzi’s latest cause célèbre (Jacob Elordi), and it’s true of the set PA Mohammed (Rish Shah), who’s convinced that he alone can “save” her.

She always was something, she never is something, and the movie around her seems unsure if that’s sustainable. On the one hand, Lillian is the only character who avoids the embarrassment that naturally attends sincerity, and there’s a palpable degree of wish fulfillment baked into a character who so convincingly doesn’t give a shit (even though everyone is obsessed with her). To paraphrase one of the people she encounters, Lillian is Teflon enough to defy a digital culture that force-feeds her a series of unworthy choices, and she emerges from every encounter unscathed… whereas other characters are liable to get their heads blown off. In a film that adopts a “South Park”-like approach to making fun of everyone, Lillian is never the butt of the joke.

On the other hand, there are a few fleeting moments in which “The Sweet East” confronts its heroine with something approaching self-awareness. Her wanton use of the word “retarded” — a slur that the Dimes Square crowd embarrassingly tried to reclaim as an expression of their freedom from liberal moralizing — feels at first like an unfortunate side effect of a movie that allegedly features appearances from Peter Vack and Betsey Brown (their names appear in the credits, but I never clocked them on screen). Later, however, someone coolly confronts Lillian about that habit, leaving her at a total loss for words. When another character snipes that they “don’t like being told things about myself,” it almost sounds like the movie is admitting to a posture of its own — that it’s recognizing that lack of belief as a belief system unto itself.

This is a fun — and sometimes very funny — movie that is virtually impossible to make fun of in return, and at the end of the day, that might be the only metric of success that matters to it.
