I like the Beasts of the Southern Wild best, but I gave both 9 out of 10. Both movies are about survival of the next generation. But Beasts never ran away from the truths, you teach the next generation. Moonrise did run away from the truths, the next generation teaching them, however compelling. So Beasts would get a 9.5, while Moonrise a 9.0.
If we can save humanity, we become the caretakers of the world
