I was at first very skeptical about the adaptation of this movie, mainly because I was in love with the robot's design in the book. But within the first two minutes, I saw that the creators clearly knew what they were doing with R.O.Z. She was robotic, careful, and most perfectly expressive for cinema.
Overall, the story was good and impactful. I do think that some scenes could have been changed further from the book to better fit a movie produced today.
