The DCEU took a beating from critics for a while — and there was certainly trouble behind-the-scenes, especially with Justice League — but even the least successful of the six DCEU movies (Justice League) made $658 million worldwide.
Meanwhile, the least successful MCU movie was The Incredible Hulk in 2008, which “only” made $263.5 million worldwide off a reported production budget of $150 million.
Halle Berry’s Catwoman only made $82.1 million in 2004 (off a reported $100 budget), and Green Lantern also only made $219.8 million worldwide in 2011 (reported $200 million budget).
Still, it is pretty rare for major superhero movies to fail these days.
