If I could re-arrange the DCEU in terms of film release, how I would do it:
1- Man of Steel (1st film of the DCEU)
2- Batman: The Dark Knight (2nd film of the DCEU)
3- Batman vs Superman: Dawn of Justice (3rd film of the DCEU)
4- Wonder Woman (4th film of the DCEU)
5- Aquaman (5th film of the DCEU)
6- Justice League (6th film of the DCEU)
Phase 1 Complete
Phase 2
7- Suicide Squad (7th film of the DCEU)
8- Shazam (8th film of the DCEU)
9- The Flash (9th film of the DCEU)
10- Man of Steel 2 (10th film of the DCEU)
11- Batman 2 (11th film of the DCEU)
12- Justice League 2 (12th film of the DCEU)
Phase 2 Complete
That is 2 phases done right there just as an example for all of you
