What is this movie — a dazzling collision of stories and genres, flashbacks and voiceovers, games and riddles — about? You might say it’s about a remarkable quartet of lead actresses (Elisa Carricajo, Valeria Correa, Pilar Gamboa and Laura Paredes) who appear in a variety of roles, capacities and situations in five of the six episodes. It’s about the enduring pleasures of narrative storytelling, but also the predictable, arbitrary nature of so many narratives. More than anything, it’s about exploding your assumptions of how movies are supposed to work. “Supposed to” has no place in the Llinás Cinematic Universe.
