This story is hard for me to understand. The detail that are not revealed in this story seems have to imagine myself. What is a unicorn? Why does the man who is run over by a bus kill an old man? Who is the child who gazes at the box? There are a lot of thought-provoking things in this movie.
Also, the action scenes were exciting, The scene of a robot which drove a motorcycle while avoiding the police car was very cool! I also felt a realistic force by the scene that the robot was blown away by crushing the bike against police cars which were blocking a street. His partially destroyed face was very impressive.
Even so, I wonder what was the unicorn. Because it could not be seen in this film, I'm interested in the beautiful contents of the box.
