That's fine. To me the success or failure of a comic book movie depends on the story and the marketing, not on which particular version of a legacy character happens to show up. I think the vast majority of the average moviegoers don't have a clue about names like Hal Jordan or John Stewart, or what a Green Lantern Corps is supposed to be. As for Geoff Johns, I believe if he truly wanted to have a solo Hal movie, he would've already tried to do so back when he was still co-running the DCEU. The buddy cop thing was announced when Johns was still "in charge", so for him to want a solo Hal flick now when he's not a decision maker anymore but just a writer, seems really far-fetched to me. Not to mention that, given WB's history with writers in the DCEU, even if Johns did produce a script with Hal as the main star, there's zero guarantee that WB would either greenlight it or preserve it the way it is. I personally think that whatever Johns ends up writing will most likely not be what we end up seeing in theaters, if that movie even manages to get off the ground.
