Superman: Earth one
Superman: Earth One was written by J. Michael Straczynski, and it’s a fresh modern take on the Superman mythos. This is one of the best Superman stories I’ve ever read, and I still re-read it every once in a while. If WB decides to do a movie where Clark Kent becomes Superman, I believe this is the best direction to go with. Also, this should be a trilogy to flesh out the story and maybe let this be the blueprint to create a cinematic universe.
