Let me start by saying that I expected a bit more. However, this movie has brilliant characteristics, especially concerning the factor of isolationism. The main character is somewhat confused, yet self-confident and seems to portray the general aspect of just-trying-to-survive perfectly. When the character realizes that there is something wrong, he made me feel like I had to go with him to explore the mystery. Another interesting aspect, is the relationship between a human and the AI. The relationship actually involves a lot around emotions - something that seems to be very underestimated in the real world concerning the relationship between man and AI. I expected a bit more from this movie in the sense that the director could have contributed more to the horror aspect. While the strong isolationist feeling is very well done, I expected that there would be stronger emphasis on the influence of derangement concerning individual psychological factors. Yet, a very well done movie that is recommended for fans of sci-fi drama and mystery.
