Love is kind of like a form of socially acceptable insanity.
This is the line that stayed with me after watching
her.
Movie Review: her
her follows the love story between a man, Theodore Twombly (Phoenix), with his highly advanced computer operating system (OS). So advanced that it was self aware and could evolve through its experiences. And with Scarlett Johansson's playful and innocent voice, it becomes pretty plausible that a guy could fall in love with it.
Who wouldn't fall in love with "her"?
