I wonder if we will see any homages to some classic COIE images,like Superman holding the dead Supergirl or Flash disintegrating as he runs through time warning of the Crisis. (Obviously those two won't happen exactly as seen in COIE)
Given the way they have treated Superman, my thinking is that they are going to kill of Hoschlin's version just so they can have her hold him like that, because you know, woke.
I'm hoping that they do not do that of course, and given that they are bringing in some iconic worlds, it is also my hope that they don't disrespect these universes by destroying any of the big ones, like Smallville Earth or Flash 90.
I suppose that if Routh isn't the same Superman from Superman Returns, then that one can go.
COIE in the comics had a purpose--to merge all the Earths into one.
They did that because after decades of stories, it was hard to keep continuity and they wanted to start fresh.
I don't think TV needs to do that. I'd like to see some permanent changes, but I don't want worlds that we won't revisit affected.
I'm not alone in being more interested in the guest stars than the actual stars, and I just hope the writers are aware of it and don't simply have cameos. Flash90 was a massive disappointment last year. They can do better.
