However, there’s an even bigger issue that this franchise needs to face, which helps explain why the box office grosses are down. The Marvel Cinematic Universe, despite being owned by Disney and getting heavily marketed to younger viewers, is no longer resonating with kids and families.
Thunderbolts* & The Fantastic Four: First Steps Struggled With Appealing To Families

At the start of summer 2025, only 31% of the Thunderbolts* opening weekend was folks under the age of 25. Just under three months later, just 15% of the opening weekend audience for The Fantastic Four: First Steps was below 18 years old. Compare that to 13 years ago, when the original Avengers had an almost exact even split between moviegoers under or over 25. Roughly 24% of that record-shattering opening weekend came from family audiences. Despite opening nearly five times as big as Thunderbolts*, meanwhile, Avengers: Endgame drew 39% of its opening weekend from folks under 25.
The MCU films were never solely appealing to the Paw Patrol crowd. From the days of Iron Man onward, these titles featured needle drops and cinematic influences (like Three Days of the Condor or John Hughes High School comedies) designed to tickle the nostalgia of folks over 35. However, the 2010s peak of MCU entertainment saw this franchise resonate more profoundly with young people. Hearththrobs like Tom Hiddleston and Sebastian Stan inspired swooning Tumblr posts around the world, while characters never before seen in live-action, like Black Panther and the Guardians of the Galaxy, absolutely belonged to this new generation of moviegoers.
Once the COVID-19 pandemic hit, though, a drastic shift occurred. New properties took over the MCU’s place as the go-to pop culture obsession for young people, while Marvel’s universe spreading across TV and movies became too much to keep track of. There was a greater emphasis on darker tones in MCU titles like Multiverse of Madness, Eternals, and Ant-Man and the Wasp: Quantumania, which have also inspired families to begin rethinking these titles as must-see entertainment.
