WHAT IF... Ben Affleck ,with either assistance or not, wrote a Batman film like no other we have ever seen before?
What if it put the emphasis back on the detective facet of Batman lore?
What if the story focused on ,not a super villain, but a serial killer instead?
It could be one from his rogues gallery that fits the story best or even a new original character.
Audience would be saying
Trying to make a movie a mystery when the villain is revealed in the marketing would seeem pointless while if he was not exploited in the marketing and not played by an actor of any standing would seem pretty underwhelming.
