When this book actually focused on Dahmer, it was insightful. Unfortunately, the text seemed disjointed. Yes, there are similarities between Thomas Harris' characters and Dahmer, but there was a considerable lack of synthesis between these motifs. The speculation of a society that idolizes and fears "monsters" seemed forced. I did enjoy the ties to Shelley, Poe, and Stevenson, but the nucleus of this book did not seem as though it had enough gravity to keep its additional parts together. The author did utilize notions of the Gothic and Foucault's theoretical work to some effect, though.
On an unrelated note, I remain bitter that I couldn't read a nonfiction graphic narrative of Dahmer or Masters' account of Dahmer instead of this--especially as Masters is cited liberally throughout the book.
