Please go and watch this movie. It is simply a masterpiece. It is the deepest look into couple relationships that I've ever seen, told in a way that is extremely captivating.
The premise is catchy: a guy falls in love with the operating system of his phone (say Siri on iPhone). Its originality takes you to the movie, but then you discover that behind the premise, a comprehensive analysis on why relationships work (or doesn't) is unfolded. You get to see all types of failed attempts at building meaningful connections, and you also go through all phases of an actually very very close bond, the one that Theodore establishes with the voice in his head, Samantha.
It may not seem the most exciting plot ever, but you find yourself always asking "what's next?" during the film. I was never bored during its 2 hours. And the film does indeed guide you from the most superficial aspects of a human relationships to places where you question your own motivations and deepest feelings, something truly remarkable in today's entertainment.
The film is so special it feels poetic. It's not only because of its depth, but also because of its form. This film is just gorgeous. Its overexposed, desaturated, low dynamic range photography fits the aseptic future perfectly. Images are crisp and beautiful, locations are impressive, color palette is fascinating, soundtrack by Arcade Fire is hypnotizing. It achieves a very difficult balance between making it all credible and making it all unique. Only the artistic design movie would be enough to watch it.
There is only one questionable decision in the film in my opinion: casting. While everyone will agree that the broken voice of Scarlett Johansson could not be better, the choice of Joaquin Phoenix seems odd to me. My mental image of Joaquin is that of a weirdo, the troubled emperor of Gladiator or the mentally ill guy in The Master. It takes time to realize that he is not a freak in Her, but quite the opposite. Perhaps it is precisely this process of understanding him that makes Joaquin the perfect choice, I don't know. I would love to hear the director (Spike Jonze) explain the rational behind.
Anyway, bottom line is: one of the most interesting films I've seen lately, one of the best of 2013, do not miss this one.
