I generally agree with the other reviewers, there's so much wrong with this movie, however they got one aspect right, for me anyway. I'm Aspergic, and like Neanderthals my brain is wired differently from neuro-typical humans. I experience the world in a different way. The portrayal of William, his interactions with other people, the way he struggles with things thing, and is an outsider trapped in a world where he doesn't belong, it all really hit home. This picture is almost a study in autism by proxy.
