The Horse Boy is a touching documentary about one Texas couple’s struggle to understand their child’s autism and find ways for all of them to cope with it. Their journey starts with Rowan’s chance encounter with a grumpy old mare on their ranch and takes us all the way to a shaman in the far reaches of Mongolia. The trip is filled with anxiety, doubt, and plenty of temper tantrums, but in the end they all agree that it was worth it and the results are amazing.
