In an interview with Collider, Gunn said that he doesn’t want the interconnectivity of the DCU to bog down the franchise or make viewers feel like they need to do “homework” in order to keep up with it.

Gunn's comments make a great deal of sense, and should allow each upcoming DCU movie to be accessible. This is an issue that has seemingly plagued some MCU projects before. For instance, The Marvels served as a sequel to Captain Marvel, Ms. Marvel and WandaVision. Perhaps this amount of homework is why The Marvels ended up being a box office bomb.

One thing James Gunn has made clear about his Superman movie is that the movie will not try to emulate the dark and edgy tone of Zack Snyder ’s Man of Steel . His movie is going to be very different in so many ways.

James Gunn has clarified one key way that the DCU’s announcement and release schedule will be different than the Marvel Cinematic Universe (MCU). Gunn and Peter Safran’s forthcoming DCU officially debuts next month with an animated Creature Commandos series.

Creature Commandos will reference events in The Suicide Squad, but that doesn't mean they exist in the same continuity. James Gunn asserts the latter isn't DCU canon despite its adopted characters and stories.

Similar is the case with DCU’s Batman, as even though the film was announced a long time ago, Gunn clarified they’ve no intentions of rushing its development without a story worth telling.
