DC Comics has been nothing if not ambitious in the last few years. The DC Rebirth relaunch was just the beginning, paving the way for a slew of new imprints like Young Animal, Wildstorm, DC Black Label and the recently revealed DC Vertigo relaunch. Then there’s “The New Age of DC Heroes,” an imprint devoted to spotlighting big-name artists and new characters. More than any other initiative this year, The New Age of DC Heroes embodies the kind of publisher DC is striving to be. That’s why it’s so unfortunate that the line has so utterly failed to live up to its promise.
