With James Gunn retooling the DCU alongside Peter Safran for modern audiences, fans are hoping they find steady footing. This is especially important given how viewers haven't been as optimistic after past failures. This has been mostly noted with The Flash and Blue Beetle in 2023, both of which underperformed at the box office despite getting decent to excellent reviews. While their futures in Gunn's DCU are still in the air, there is still a light at the end of the tunnel, thanks to current excitement for Gunn's upcoming film, Superman: Legacy.
