Just watched The Batman
-I think I understand why DJT says he is Batman.
Batman was the link between the Riddler, and legitimate justice for the corrupted government.
The Riddler said unmasking it wasn't enough, so he made everyone see, at a great cost to Gotham. The Riddler's Anons blasted the message to the public, violently -because the Riddler was after all insane in that story. A trickle also turned into a great flood.
Not a great film, IMO -but 'm glad I watched it for the illustration.
