Despite positive reviews and a great Rotten Tomatoes score, Fantastic Four: First Steps had a massive second weekend drop at the global box office

The Fantastic Four: First Steps has suffered a pretty significant drop at the global box office in just its second week – and it's possible that superhero fatigue is truly and finally upon us.

According to Variety, the new Marvel film saw a 66% drop in its second weekend, earning just $40 million from 4,125 theaters. The film opened with $117.6 million, against an estimated budget of over $200 million. As it stands, the film has earned a total of $386 million globally, which is great, but not great for Marvel, which has produced some of the highest-grossing films of all time with Avengers: Infinity War and Avengers: Endgame each bringing in a cool $2 billion.

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.

In terms of superfatigue, Superman, which marks the first feature-length project in James Gunn and Peter Safran's DCU, debuted to $125 million and saw a 54% drop in its second weekend. The movie is currently sitting on a $551 million global box office, though Gunn says lower global box office returns are due to the fact that Superman isn't as widely recognized worldwide as he is in America.
