The DCEU's final release – Aquaman and the Lost Kingdom – makes a disappointing box office result official, leading this cinematic universe to end with a thud instead of a bang. The DCEU is about to be rebooted into the DCU by James Gunn and Peter Safran, and 2023 proved that the reboot is happening at the right time. Shazam: Fury of the Gods, The Flash, and Blue Beetle all flopped at the box office, costing DC and Warner Bros. hundreds of millions of dollars. Aquaman and the Lost Kingdom was the DCEU's final hope, and it didn't perform much better.
