Socially accepted insanity

A man (Joaquin Phoenix) falls in love with an operating system (the voice of Scarlett Johansson). And vice versa. The real funny and absurd shit starts when the human starts to get to the operating system's nerves ("I need some time to think"), when o.s. begins to resemble an actual woman, showing human emotions, even wanting to meet other humans or, in fact, operating systems. Yes, it's a Spike Jonze picture alright, bits of Being John Malkovich brilliancy, funny as fuck.
