Spanish director Pau Faus beautifully juxtaposes two vastly different worlds without falling into an overly simplified good/bad opposition. The contemporary relationship between humans and animals is more complex than that. Shepherd Valeriano, for instance, has a joint disease that causes him a lot of pain. He could never sustain his current, idyllic life without the many pills he takes, pills presumably developed in a a science lab. Julia reveals that the lab, while chilly, is also filled with deeply humane passion and frustration from the desperate hunt to find a vaccine. Seamless transitions from one world to another highlight the absurdity and provide a fascinating reflection on the many contradictions in the relationship between humans, science and nature.
