Wonderful! 
I went directly to Netficks and popped it in the cue.  I have pondered a question for many years and while Whale Rider and Eagle Huntress comes closer to the question it doesn't quite ask it --

 "How is the 'hero's journey' different when it is taken by a woman rather than a man."? Or a woman is compelled to take a hero's journey that none other would take for the sake of the community.

 The hero's journey is a long loved story telling structure both in fact and in fiction. But, for women -- ahh, there is a difference. Films such as this are so rare. Not only is there a visual feast to rest eyes in but there is that 'first woman to ever' extraordinary circle of women bearing witness to join and to celebrate.
