Holly Williams from The Observer:

Antkind is 706 pages long. It offers a maximalist satire of a contemporary America defined by fake news, corporate bullshit, vacuous pop culture and performative wokeness, but one so excessive, surreal and repetitive that it is itself tiresomely bloated and absolutely exhausting. If anything can happen without consequence, stakes are lowered. It’s absurdism ad infinitum.

Where Kaufman’s films are playfully mind-bending, they usually have real heart. But although Antkind is skippingly clever – saturated with comic allusions, puns, linguistic inventiveness and wildly unfettered imagination – it is sorely lacking characters you actually care about or any emotional narrative to cling to.

BOOOOO.

Ah well. The initial universal acclaim was bound to give way to a few negative reviews, eh. Charlie is never for everyone.
