Peter Debruge Chief Film Critic Depending on how you look at it, “Ponyboi” is either a Trojan horse for exploring nonbinary gender identity or a hackneyed crime movie with a radically unorthodox queer protagonist. Either way, it’s a sordid yet stylish showcase for intersex actor (and activist) River Gallo, who uses “they/them” pronouns and sees the project as an opportunity to educate audiences about the social and psychological aspects of exhibiting both male and female traits in a world that classifies people in one box or the other.
