I personally don't think 'The Near Apocalypse of 09' should ever be portrayed and instead left to our imaginations. Given the status of Thanagar and I believe the existence of Adam Strange at the time the Rann-Thanagar war occurs, I do believe it would b interesting to see it portrayed in a movie. Infact it might be cool to have one character such as Hawkgirl for example to say "this like the the near apocalypse of '09?" and then have John Stewart reply with "worse" or "makes this look like a walk in the park".
