This is one of the best thought provoking movies I've ever seen. Many may not understand or relate to it, because it is so far in the distant future. What will become of humanity? It may the most sense of all AI movies. Most will like the Matrix and Terminator for the action, but that is hidden in this movie. Just like the daughter doesn't understand what happened before she was born or what happened outside the facility. What does it mean to be human? How can we protect humanity? So many good questions.
