"The reviewer isn't quite right that both film and book exist to indulge the viewer/reader in a pure experience of misery. Like a lot of McCarthy's work, The Road creates a world of such infinite darkness, a void in fact, so as to make the one spot of light, of love, that exists in this void of "outer dark" through which the character wanders all the more heartbreakingly, all encompassingly vital. There's an exchange near the beginning of the book, when the boy asks the father what he would do if he (the boy) died, and the father simply explains that he would want to die too. Hillcoat cut this scene from the film, but after he and screenwriter Joe Penhall privately screened the film to McCarthy, McCarthy asked for the exchange to be reinserted, explaining that this exchange embodies what the film is about. The film, and book, then are not just about misery. They are about the eternal misery that lies beyond the one tiny speck of love and meaning, and in that respect they absolutely are about the importance of love. See Tommy Lee Jones's final monologue in No Country For Old Men for another example of this theme in McCarthy's work."
