As a game developer whose work has been greatly influenced by Mr. Kojima, I can say that the film is a light of hope for new creative directors. It shows many ideas: giving feedback of everything, 200 decisions per day, having people that support you no matter what, showing your inner world and having a particular worldview, edgy game but for the masses...
It also communicates the importance of art: enhance the human spirit and inspire. The film was entertaining. It was really nice to receive a rope in a world of sticks. It is a must if you admire Kojima as a creative director. You will also see some early scenes of Death Stranding.
