Charles McGrath, an editor of the New York Times Book Review, wrote in a 2004 essay "Not Funnies," that comic books are "what novels used to be an- accessible, vernacular form with mass appeal." He says that if the "highbrows" are right, they are a "form perfectly suited to our dumbed-down culture and collective attention deficit." How might Scott McCloud respond to McGrath and the "highbrows"? How does McCloud address the gap between high and low culture?
