As darkly-hued as Fincher and Sorkin's views of entrepreneurial ethics and interpersonal morality are in The Social Network, the score that Reznor and Ross provide pushes the film into even deeper shadows and suggests an outline of technological panic in the human psyche that gives the film's critique of the social web a sharper edge than it would have had without it. No filmmaker could ever ask for more.
With help from producer Atticus Ross, Reznor has made a solid soundtrack to David Fincher's movie by doing what he's always done: creating grand industrial rock.
