Politically, Clint Eastwood is a giant in the midst of a horde of Hollywood dwarfs. A man that is by himself a symbol of the greatest values and ideas that make up America's most important gift to humanity. "Gran Torino" shows it in many levels. His treatment of the question of prejudice is magnificent. As a versed libertarian, he knows that being human means being imperfect and prejudiced, but also being innately capable of redemption and of finding sympathy in apparent dissimilarity. The movie also gracefully shows how bigotry at the individual level is by far much less dangerous than the social evils that will always arise from institutionalized privileges created by the coercive powers of the state, independently of their good or bad intentions.
If you haven't yet watched this marvellous movie, make sure that you do it. Enjoy the trailer.
