Moving forward, this suggests fans will get to see the origins for future heroes like Flash, Cyborg, Aquaman, and more.
Man of Steel used flashbacks to critical moments that helped shape Clark into the man who would become Superman.
Again, the use of flashbacks and flashforwards are already nothing new to the DCEU.
Hopefully the studio has a great idea how to incorporate both of these moving forward, and fans can prepare now for more flashbacks/flashforwards in the future.
