After many sci-fi movies, Ad Astra attempts to be something deeper with many references to loneliness and the sick desire to make a huge discovery. When Roy McBride was a kid, his father left the Earth to discover artificial life. Many years later, after the apparent death of the astronaut, Roy undertakes a mission to stop the emission of cosmic rays that are caused by the spaceship of old McBride. Director James Grey created a brilliant vision of the future, with facilities on Mars, commercial trips to the Moon and war for resources. The movie shows the weaknesses of humankind and our place in the Universe. Who would have dreamt that a blockbuster would try to answer such questions about human existence?
