We've been seeing it for the last seven years:
- JL and SS were reshot because WB was surprised by the negative reception to BvS.
- Snyder being forced to reshoot JL and being forced our by WB? Because they wanted a course correction.
- JL failing to even crack $100M on OW? A direct result of audiences feeling burned by BvS, the film setting it up. Josstice League didn't kill the DCEU, it was proof that it had already been dead.
- WW, The Batman, Joker, and AM were hits despite the baggage the brand had, in part, because they had positive word of mouth. They're the exception, not the norm.
- The reason why James Gunn and Peter Safran were brought in (after numerous regime changes)? Because the main franchise had so much baggage that the only option was to start anew.
