Marvel’s First Family might not save the day after all. “The Fantastic Four: First Steps” is quickly losing steam in its second weekend, signaling the comic book adventure isn’t connecting at the box office beyond the film’s core demographic of superhero fans.

First Steps ’ second-week ticket sales called it a cratering, and noted that its week-to-week drop was akin to similar stumbles for past Marvel pariahs Ant-Man and the Wasp: Quantumania and Thor: Love and Thunder.

Captain America: Brave New World and Thunderbolts also saw so-so box office returns, with the former earning $415 million globally and the latter taking home $386 million. The lowest-grossing Marvel movie of all time is The Marvels, which just broke even at $206 million globally, with 2012's The Incredible Hulk coming in second at $265 million.
