If this universe takes off and actually becomes a universe much like Marvel, then what should the DC movie opening intro look like before the movie starts? For me I would make it similar to Marvel in the sense you give it a good intro like an iconic epic opera/rock theme and in the highlights you showcase every superhero in the universe but also in that same intro you show highlights of whatever DCU movie you're set to watch...similar to how Marvel's opening intro is. Under Gunn, you have somewhat of a similar opening intro but DC style with the DC emblem popping up on the screen.
