WB should release The Flash movie as it is (no visual replacement) once the planned visual effects and post-production are finished, but make it a limited special release event where the stream it for free on several services as well as their own HBO Max, but also do a large theatrical release where the gross profits are donated to various charities that probably have some things to say about Ezra Miller's actions (maybe this way they're able to make it not a total-loss and even build goodwill and support going forward). Make it a big talking point in their advertising, lean extra extra hard into it with their publicity. Blast out something like, "We're disappointed by the problematic behaviors of our lead, and do not support them whatsoever in their continued avoidance of cooperation with the appropriate authorities regarding their personal matters. That said, they are just one person amongst the many hundreds who also have put effort, time, and passion into this project, and we feel it would be unjust to those creators, as well as the many long-waiting fans, if we were to keep this from them due to the unfortunate and irresponsible actions of one person."
