While some critics dismissed Romero's film because of the graphic scenes, writer R. H. W. Dillard claimed that the "open-eyed detailing" of taboo heightened the film's success. He asks, "What girl has not, at one time or another, wished to kill her mother? And Karen, in the film, offers a particularly vivid opportunity to commit the forbidden deed vicariously." Romero featured social taboos as key themes, particularly cannibalism. Although zombie cannibals were inspired by Matheson's "I Am Legend", film historian Robin Wood sees the flesh-eating scenes of "Night of the Living Dead" as a late-1960s critique of American capitalism. Wood asserts that the zombies represent capitalists, and "cannibalism represents the ultimate in possessiveness, hence the logical end of human relations under capitalism". He argues that the zombies' victims symbolized the repression of "the Other" in bourgeois American society, namely activists in the civil rights movement, feminists, homosexuals, and counterculturalists in general.
