First off the movie is long and slow but it's gorgeous and thoughtful and posits a number of ideas related to AI and human/machine relationships once we've figured out how to surpass the uncanny valley and create unmistakably human like androids. How will they feel? Will they love, can we love them? What is love anyway? Both Ewan Macgregor and Lea Seydoux are stellar as they explore love, jealousy and loss between human and sentient machine. If you're patient and thoughtful, a very rewarding film.
