But it doesn't change the fact that as of right now, the Arrowverse shows consider the other shows and movies shows part of it's multiverse.
Yes, of course they do. I'm just saying that doesn't obligate any
other DC production to reciprocate. Many people online, including writers for clickbaity comics-news sites, are saying that Ezra Miller's appearance in
Crisis somehow proves that all DC continuities are now "officially" one, that the movies will now be guaranteed to acknowledge the Arrowverse, that the fictitious conceits of this specific story will be binding on every other DC production from now on. And that's just a fundamental misunderstanding of how fiction works.
Although this is a different situation since in this case there are these productions are all from the same companies, and in several cases the same producers, so there are at least a few people involved in both productions who are aware of what's going on.
Yes, but the same creator can work in multiple different continuities -- e.g. Marv Wolfman co-writing
Crisis Part IV, which is clearly a different continuity from the original CoIE that he wrote. Or Kirsten Beyer co-creating
Star Trek Picard, which disregards the Pocket novel continuity that she spent years writing for. Or Timothy Zahn writing a new
Star Wars Thrawn trilogy to replace the original one he wrote.
The reason for having different continuities is
not lack of "awareness." It's understanding that different works of fiction in different venues are meant for different audiences. There may be overlap between them, but the whole
point of doing different versions of a thing is specifically to attract a wider, more diverse audience than you'd get with just one version. So having the different versions be distinct from each other is a plus. You want each version to be able to stand as an independent entity and tell its stories the way it needs to.
The only thing that seems a bit wonky is Jonn being able to restore the individual memories completely as to what happened before and during the Crisis. To do it the way they have been, it would imply Jonn completely read the mind of everyone involved during the Crisis (even the parts he wasn't involved in) and was able to separate them and restore them completely. <---- That's one hell of a telepathic ability even for Jonn.
I remarked on that earlier in the thread. We have seen Arrowverse characters able to recover people's memories from erased timelines before, notably Vibe and Savitar/Alchemy.
So the Smallville earth is still gone or unknown?
The producers assure us it's still there. I think we can safely assume that all the Multiverse was restored, except for the few Earths that were merged.
