In the early days of the new DCU after COIE, things were quite well done in the way the new combined DCU were potrayed. Sadly over the years things went a little haywire (see Donna Troy, Hawkman and Supergirl a little). It could not be helped though and I am sure it was not intentional. Now I really feel that after FC, we should see the return of the original multiverse. Not the new one after IC but the actual one before COIE. I really would not mind reading about different sets of heroes in different Earths. Sort of reading about DCu at one time and then Dark Hourse in another and then Wildstorm. With good writing it can be interesting and we can have the occasional crossovers.
The only thing is how to explain the continuity from 1985 till now when everyone was in one Earth when so many heroes lives affected others? Any thoughts there?
