Film critic David Thomson's 1995 article on Schwarzenegger, referenced here before, seems more prophetic each time I read it. There's a paragraph where Thomson notes that Schwarzenegger has had to deal with a lot of abuse and mockery, but has responded by sequestering it in "some dumping ground of the soul" and grinning even more broadly, becoming even more self-deprecating, even becoming a Kennedy by marriage. "And wonder if, for all the bomhomie," Thomson notes, "there isn't yet a seed of revenge -- a seed as revolutionary as those Jack got for his cow..."

Not the most elegant simile, perhaps, but the insight isn't a bad one.
