Atsushi Nishigori’s “Grotesqqque,” an original anime from studio Clover Works consisting of three short films, is a hyperactive mish-mash that’s uneven and overwhelming, but ultimately fun.

Anthology films like this have a long history. The bubble-era 1980s, in particular, when funding for experimental animation was flowing like champagne, spawned sci-fi classics like “Robot Carnival” and “Neo Tokyo” that gave up-and-comers some early directorial experience.
