I am not much of a fan of the Sci-fi genre, but this film kept me entertained while sitting on a plane. It is based on a book by Isaac Asimonov, who was clearly informed about the debates philosophers carried out over the last 5 decades concerning artificial intelligence. Will it ever be possible for robots to think and feel like human beings? Robots have become so cheap and so sophisticated in Chicago of 2035 that people buy them in electronic stores as cheap labor. Will Smith plays a cop who does not like robots and suspects that they are not as peaceful and moral as the largest manufacturer, US Robotics claims. The chief scientist of US Robotics is found dead after falling down 30 stories into the courtyard of the U.S. Robotics firm.  Will Smith correctly believes that the apparent suicide was murder but who did it? Could a robot ever turn against the human creators?
