However, not all reception has been positive; the book has had its share of critics. Rohrer writes, "Many of these readers are disappointed that the novel fails to meet the expectations generated by the mystique it is shrouded in. J. D. Salinger has done his part to enhance this mystique. That is to say, he has done nothing."  Rohrer assessed the reasons behind both the popularity and criticism of the book, saying that it "captures existential teenage angst" and has a "complex central character" and "accessible conversational style"; while at the same time some readers may dislike the "use of 1940s New York vernacular" and other things.
