Diego García’s widescreen cinematography is almost stunning enough to hold one’s interest for the entirety of this self-regarding three-hour drama by Mexican writer-director Carlos Reygadas (Silent Light); the story, however, will likely try your patience well before it ends. Reygadas and his real-life wife, Natalia López, star as a married couple who live on a cattle ranch with their three children; she manages the ranch while he writes world-famous poetry. The couple also enjoys an open relationship, which the film depicts salaciously in spite of its arty veneer. When the husband starts to suspect that his wife is getting attached to one of her lovers, he slowly loses control over his life, and the marriage disintegrates. As a filmmaker, Reygadas dresses up the soap opera narrative with lots of the poetic imagery and sound design on which he built his reputation; some of it’s spellbinding (like a long take filmed from the bottom of an airplane), but much of it feels self-important and overstated. Reygadas is nothing if not ambitious—when he fails, he fails big. In English and subtitled Spanish.
