Background: The Dark Knight Returns (alternatively titled Batman: The Dark Knight Returns) is a 1986 four-issue comic book miniseries starring Batman, written by Frank Miller, illustrated by Miller and Klaus Janson, and published by DC Comics. When the series was collected into a single volume later that year, the story title for the first issue was applied to the entire series. The Dark Knight Returns tells an alternative story of Bruce Wayne, who at 55 years old returns from retirement to fight crime and faces opposition from the Gotham City police force and the United States government.
Context: Despite the cost of the single-issue packaging, The Dark Knight Returns sold well. Priced at $2.95 an issue, DC Comics promoted The Dark Knight Returns as a "thought-provoking action story". Time said the series' depiction of a "semi-retired Batman [who] is unsure about his crime-fighting abilities" was an example of trying to appeal to "today's skeptical readers".  IGN Comics ranked The Dark Knight Returns first on a list of the 25 greatest Batman graphic novels and called The Dark Knight Returns "a true masterpiece of storytelling" with "[s]cene after unforgettable scene." In 2005, Time chose the collected edition as one of the 10 best English language graphic novels ever written. Forbidden Planet placed the collected issue at number one on its "50 Best of the Best Graphic Novels" list. Writer Matthew K. Manning in the "1980s" chapter of DC Comics Year By Year A Visual Chronicle (2010) called the series "arguably the best Batman story of all time." It was placed second in a poll among comic book academics conducted by the Sequart Organization.  The series also garnered some negative reviews. In April 2010, Nicolas Slayton from Comics Bulletin ranked The Dark Knight Returns second in his Tuesday Top Ten feature's Top 10 Overrated Comic Books behind Watchmen. Slayton wrote, "[t]here is no central plot to the comic, leaving only a forced fight scene between Superman and Batman as an out of place climax to the story." "Gone are the traits that define Batman," also citing "misuse of the central character." The New York Times gave the 1987 collected release of the series a negative review. Mordecai Richler felt that The Dark Knight Returns was not as imaginative as the work of Batman creator Bob Kane. Richler commented, "The stories are convoluted, difficult to follow and crammed with far too much text. The drawings offer a grotesquely muscle-bound Batman and Superman, not the lovable champions of old." He concluded, "If this book is meant for kids, I doubt that they will be pleased. If it is aimed at adults, they are not the sort I want to drink with."
