I originally had no intention of watching this movie, because after reading the book I was pretty sure watching a film version would be a lot like emotional self-flagellation. I was therefore a bit surprised at myself when I did decide to watch it.
The film, directed by John Hilcoat, is everything an apocalyptic film should be in a cinematic sense--dark and barren landscapes emphasize the struggles of the characters. Viggo Mortensen does a superb job of portraying a man whose sole concern is the well-being of his child in the face of a dying planet. Kodi Smit-McPhee plays the man's son and is absolutely fantastic, especially considering he is an Australian performing with an American accent throughout the whole film. In fact, the entire production is incredibly true to the novel in most respects, although the mother (Charlize Theron) plays a much more prominent role than she does in the book.
There are cannibals and calamites and Coca Cola. I would highly recomend this film.
