In a surprising turn of events, Marvel Studios and Disney's highly anticipated superhero sequel, 'The Marvels,' has stumbled at the box office, marking a historic low for the Marvel Cinematic Universe (MCU). The film, with a production budget of $200 million, opened to a mere $47 million domestically, raising questions about the impact of potential superhero fatigue among audiences. This unexpected setback not only falls short of past MCU triumphs but also raises concerns about the evolving dynamics of the superhero film landscape.
