Marvel's Biggest Post-Endgame Mistake

TL;DR

Marvel's biggest post-Endgame mistake was opening Phase 4 with a late, unnecessary Black Widow prequel instead of letting the MCU breathe and rebuild.

Key Points

• 1.Black Widow was the wrong film to launch Phase 4. Releasing a prequel starring a character already dead in Endgame — a movie fans had demanded for years but got too late — set the entire phase off on the wrong foot.
• 2.Marvel should have paused and let Endgame breathe. Instead of a 5-year rebuilding window with fresh characters, Disney pushed rushed TV shows and underbaked movies, training audiences to expect only cameos and crossover payoffs.
• 3.Comic publishing history offered a clear blueprint Marvel ignored. Post-crossover events like DC's Brightest Day and Marvel's Dark Reign used sub-banners to signal a new era and introduce repositioned characters — Marvel did nothing equivalent after Endgame.
• 4.Phase 4's individual entries failed to build a coherent new foundation. Falcon and Winter Soldier could have been a prologue; What If?, Hawkeye, and Eternals underperformed; Shang-Chi had no follow-up — Marvel never messaged it was in a rebuilding era.
• 5.The lack of narrative infrastructure now threatens Doomsday and Secret Wars. Without an established new Avengers team or buildup for Kang, Marvel is forcing a massive crossover without the framework needed, making creative success nearly impossible.
