The MCU didn’t collapse overnight. It started with one small decision...opening Phase 4 with a Black Widow prequel. Black Widow wasn’t just a late solo movie, it was a signal that Kevin Feige and Marvel Studios didn’t have a clear plan for what came next. After the massive success of Avengers: Endgame, Marvel had a chance to reset, introduce new heroes, and define a bold new future. Instead, they looked backward. And that decision set the entirety of Phase 4 off on the wrong foot.
