The cancelation of Man of Steel 2 was controversial among the DC fan base. Henry Cavill starred as the new Superman for many years, but some fans took issue with the films he was in. Numerous moviegoers have expressed their disapproval of new DC Studios head James Gunn getting rid of the previous Superman, making the past decade of films essentially irrelevant. Despite Gunn's actions causing this rage, the cancelation and Henry Cavill's departure can ultimately be tied back to Zack Snyder.
