After 'Un Buen Día' is a documentary about guilty pleasures, ironic consumption, and love for art. There's a common saying that when an artist finishes a work, it no longer belongs to them. It begins to take on a life of its own, becoming part of the world, and only then does it find its true meaning. This is the story of a successful family of artists and an unlikely blended family, told through what some consider the worst Argentine film in history and what others view as an object of devotion.
