Just do a decent Batman show… straight up. No ‘prequel’, no ‘origin story’, and no ‘untold story of Aunt Harriet being a spy in the Vietnam war’ (I’m looking at you “Pennyworth”).
Give us a decent 1 hr show where sometimes it’s a mystery and other times action-focused…but just Batman. No Batman family (maybe Robin in like a 3rd season), no Huntress, and Gordon as a supporting character only. Follow Dennis O’Neil Batman Code (no killing), and make him a relatable, interesting character. Focus on his mission, keeping his Bruce Wayne persona, and how he maintains his double identity. Make him a detective, a caped crusader, more than a dark knight (put the grittiness and violence aside for once).
There would be so many great stories… but unfortunately the likelihood of something like this happening is 0.000000000000001%.
