Aquaman and the Lost Kingdom's box office performance is a good sign for the King of Atlantis' future in James Gunn's DCU reboot. After a string of critical and commercial disappointments, the DCEU's last hope to end on a high note rested on James Wan's Aquaman and the Lost Kingdom, which chose not to include any nods to the rest of the DCEU and instead focused on Aquaman and Atlantis. But while Aquaman and the Lost Kingdom's cast, self-contained plot, and connection to the highly popular Aquaman were always in its favor, the sequel faced an uphill battle at the box office due to DC's recent unfortunate streak.
