In 2019, Marvel Studios reached the top of Hollywood with Avengers: Endgame — one of the highest-grossing films in history. The MCU had built a $32 billion empire that felt completely unstoppable. But just a few years later, that empire started cracking. Box office bombs. Disney+ overload. The Multiverse Saga confusion. The Kang controversy. Creative burnout. Audience fatigue. So what actually killed the MCU? In this video, we break down the real reasons behind Marvel’s downfall — from the perfection of the Infinity Saga to the chaos of Phase 4 and Phase 5.
