Beautifully complex, open-hearted examination of the human condition- particularly of loneliness and the urge to connect with a world full of strangers who are much more likely to misunderstand you than not. The initial hook describing the main character Chihiro as a former sex worker turns out to be almost completely "irrelevant" to the story. It's not what you (may have) thought this film would be about. It's about learning to appreciate every fibre of every human being you meet - a feat most people aren't actually capable of.
This is film of quiet contemplation, quiet conversation and quiet thoughts - the fact that most of the film has no music soundtrack allows you to truly absorb and appreciate every character's words and underlying motivations, particularly of course, of Chihiro's, as she gracefully glides from person to person, reflecting their inner goodness in her own.
I rated this 9 until I reached the end. It deserves a 10.
