Yeah you wouldn't get a movie like Ang Lee's Hulk, Burton's Batman Returns, or hell, even Singer's X-Men or Nolan TDK films nowadays. That we even got Reeves' Batman and Phillips' Joker, imo the only 'recent' superhero films that were idiosyncratic and reflective enough of the directors' vision that they could be considered analogous to those already mentioned, was a miracle born out of that perfect sweet spot moment where the DCEU had basically been given up on and left to drown, before WB ill-advisedly reached back in at the last second to give it CPR. Cinematic universes are the death knell for superhero films as personal, creative and unique as the ones mentioned already. Even both the MCU and DCEU themselves were both born out of fairly unique films that were never originally designed to be fitted neatly alongside other movies on an interchangable cavalcade.
