Fans like to complain. Comic book movie fans really like to complain. And DC Studios fans basically live to complain online. OK, not ALL of them. But given the volume of grievances logged by DC fans on social channels over the years—especially as they watch all the DC Films in order—it’s safe to say they are a “Prove It To Us” fanbase. Which is what current DC Films Co-President James Gunn tries to do. He explains his decisions. He practices transparency. And when fans have questions, he usually answers them online.

Like when casting announcements started rolling out regarding co-stars for James Gunn’s planned "Superman: Legacy," a few people started to gripe. The issue became the addition of characters like Green Lantern (Nathan Fillion) and Hawkgirl (Isabela Merced), which some Superman fans already feel is going to steal focus away from the Man of Steel. Why can’t "Superman: Legacy" just be a movie about Superman? And it can be! Which is why Gunn’s explanation for the inclusion of these characters makes all the sense in the world.
