If you could start over with the DC cinematic universe, how would you structure it? Would you keep it as is, soft reboot, or from scratch?
I would re-launch the main characters–batman, superman, wonder woman, etc.–in there own stand alone movies with no mention of the existence of each other in their own continuity, until at least 2-3 movies in…if they were successful on their own. I would set up rules about what the stakes could be in their solo movies. For instance, there would not be any global stakes in the introductory films, just city or less. This way, they would not be expected to know one another in the course of their solo runs, if I decide later to bring them together. Essentially, all the solo stories would be self-contained and in, conceivably, their own worlds until they were proven successes.
For characters like booster gold, green arrow, and blue beetle, they would be allowed to do team/ensemble movies because this might create a greater likelihood for success with those characters that otherwise might not make it in a solo film. But, they would exist as if in their own universe as a team initially.
As the movies succeeded on their own, I would construct an interweaving plot on the already established characters and story arcs, leading up to a Justice League or Infinite Crisis type plot. And, for kicks, my ultimate climax and culminating story would be something like Kingdom Come, if everything goes according to plans.
What would you do?
