The Marvel Cinematic Universe has had an unbreakable grip on pop culture since it first began in 2008. Recently, however, the atmosphere around the MCU has been shifting a bit. Guardians of the Galaxy Vol. 3 performed well at the box office, but not as well as films such as Barbie or The Super Mario Bros. Movie. Meanwhile, Ant-Man and the Wasp: Quantumania underperformed while The Marvels is expected to do the same.
