I've seen reviews by 'critics' who hated it, hated Graham Greene's character, etc. They don't like it because he's not the happy-go-lucky smiling injun they want to see. It's obvious Arthur is not human, but a personification, or materialization, of Peter's sweatlodge vision. "You dreamed anger, and your anger is real"...and it's taken on a life of it's own. When his work is done, when he's taught Peter to take more than a passive stance, he returns to his world. But you also see that spirit is going to be carried into future generations by the precocious Polly, the little girl at the beginning and end of the film. I love Budd's babbling once pain/infection/delirium takes place. And I hope his ordeal has taught him a thing or two about his cavalier destruction of not only the land, but aboriginal rights and greed.
