re: Who can lead the DC Film Universe? Obvious Solution....

They could absolutely handle it if they wanted to. Give them six months to immerse themselves in DC lore if they aren't already, then six months to plot out main arcs, then have them head a writer's conglomeration to churn out good scripts. Hell, they could probably do it themselves.

They have source material, just like GOT. They've proven themselves more than capable of adapting material to the screen. This would be a brilliant move by DC and WB
