"Her"

Ok, the movie about the man falling in love with his OS actually turned out to be a heartbreaking masterpiece. "She" (the OS) doesn't have a physical body, but in every other respect is a fully realized person (within the context of the world of the film--that is, leaving aside theological questions of the nature of the soul). This allows a very unique perspective from which to consider the essence and meaning of love. In a way, it reminds me of Lars and the Real Girl although it's by no means derivative: two unique and beautiful approaches to the same question. In fact, I'd recommend seeing them both together, if you haven't seen either. And maybe even if you have.
