It’s telling Chris Rock took his blistering Hollywood indictment “out of town,” world-premiering it before festival audiences in Toronto. Unfortunately, his bleak portrait of the dream factory proves too unfocused to fully satisfy critics, insiders or general audiences wherever it plays. Writer/director Rock’s Misty Green (C-) peaks during its opening credits, pairing Hollywood imagery with “If My Friends Could See Me Now” before revealing how badly show business has failed its title character. Rosalind Eleazar is captivating and game for every demand of an oddly written role, playing a once-promising actress battling drugs, humiliating auditions and poor choices exacerbated by bad influences embodied by ensemble mates Anna Kendrick, Adam Driver and Daniel Kaluuya. Rock plays the man who keeps giving Misty another chance, delivering wry commentary that sometimes feels more like stand-up being workshopped than a character’s depths being plumbed. Topher Grace and Tracie Thoms add texture as industry figures, while two diegetic numbers featuring songs from Radiohead and Dreamgirls let Eleazar flex even more of her formidable talents. Yet the film forgets its own eviction countdown, never clarifies whether it means to excuse, expose or skewer L.A. life and fails to assemble its intriguing pieces into a cogent portrait. Eleazar keeps Misty Green eminently watchable, but far more of the film lands like “Creep” than sustaining the “One Night Only” glory.
