The DC Universe looks to come out swinging in the wake of the less-than-graceful departure of its predecessor, the DCEU. The presence of James Gunn as one of the project's creative leads, as well as comics-savvy titles like The Brave and the Bold and Superman: Legacy, suggests that the new franchise will show far more affection for the source comics, as well as delivering characters who haven't enjoyed as much time in the spotlight as stalwarts like Batman and Superman.
