Similar in tone to Aldous Huxley's Brave New World - the action is divided between a controlled social system that delegates law and order inside the city to a central computer, and an unmonitored outside zone. The design of the city settings is minimalist Stepford-wife suburban and rather stylised (it reminded me a little of the Good Place - a colourful and safe, yet socially stifling and souless utopia). The outside scenes are more redolent of contemporary Brazilian backstreets (or how those are depicted in other Brazilian movies I've seen). I enjoyed the contrast - which is very clear. As another reviewer said, it's essentially a Brazilian Black Mirror. But it has its own flavour and Carla Salle is rather compelling in the central role.
