Many more brains than 95% of movies its type. Much of the technology is here already or only a few years away. The purpose is to raise many questions not only about technology but about America’s role in this fracturing world and about individual morality. Very good acting for a sci-fi movie. A major plus is that the two leading, complex roles are played by black actors. Negative reviews are by people who can’t read between the lines and don’t know what good sci-fi is about.
