Probably the most gender-not-in-the-picture movie about a girl-child that you will ever know. Beasts of the Southern Wild (2012, Benh Zeitlin) is at the same time scary (be aware of the possible trigger of very rough kind of parenting) and somehow inspiring...
If you treat it as a metaphor (yes, again, as with Picnic at Hanging Rock) - and not as an actual story of a small child wandering around, lost and scared - it is a journey of a free person in the big, wide world. Occasional damage is caused, being nature and all, but things somehow make sense, there are people you can trust and even the scariest monsters (storms, police, actual monsters) can be tamed if you stand brave and look them into eye.
An additional gem is the very young Quvenzhané Wallis who we are waiting to see in upcoming movies. While so, she's already known for not playing dumb nor fake humble. And having been nominated for a Best Actress Oscar when you're 9 is, well, AWESOME!
