The WW84 set footage of the riot, add in the first WW film, plus JL, with a dab of AQUAMAN kind of tells you that the current continuity is toast. The Snyder verse technically died with WONDER WOMAN.
As far as I know, JL and Aquaman don't have things in them that contradict continuity. The tone for JL may be different, but I don't think continuity was affected. As for the first WW film, continuity wasn't changed for that either. A vague thing said was followed by another vague thing. The WW84 footage would contradict the first WW movie as much as it would contradict other DCEU movies in terms of Diana being a public superhero, but Diana helping people has always been a part of continuity; she helped fight Doomday, as I'm sure you recall. Since we don't know the context of what's happening in WW84, there could be reasons why whatever happens in public isn't perceived or remembered. Magic is involved after all.
I mean, yeah. I sort of shrugged off WONDER WOMAN being different but looking back, the final words by Diana in that film are in direct contradiction to BvS. JUSTICE LEAGUE tied itself in knots trying to have it both ways; stay in continuity with both films. And now we see these set videos and Diana is in broad daylight during a protest/riot sequence. That settled that debate.
WW wasn't different. In BvS, Diana is speaking to Bruce in response to a question about whether or not she would come together with other heroes. She explains that she walked away from mankind because she didn't think could stand together with them. At the end of WW, Diana still believes this. She believes that no hero can defeat mankind's darkness, so she will believe in love and protect them, but she won't lead them or team up with them like she did with Steve and his comrades.
JL carried this forward by having Diana speak about her worries about being a leader. Diana had walked away and not stood with mankind as its leader or as a partner and chose to work alone. For WW84, Diana may be doing things in public, but it's not clear how those events will be remembered or reported on by those who witness them. Until we see the movie, I don't things are completely settled.
Hell, theres tons of instances in JUSTICE LEAGUE that are out of continuity.
Like what? The mother box thing? Most of that is minor stuff that I can see filmmakers doing out of ignorance or handwaving as not significant enough to factor into their decisions. Messing with Wonder Woman would mess with the whole foundation.
And now we know that when AQUAMAN starts, hes in Maine. That makes no sense to me, considering the final image of Arthur in JL.
Wasn't the final image of him swimming away? That's too generic to specifically relate to anything. Why couldn't he be settled in Maine now? Either it's a place he's been to before that he is revisiting or he decided to move. He seemed kind of itinerant, so I don't know why his location changing means anything other than he moved. Pre-Aquaman Arthur on
Smallville was quite similar actually. He moved around the world trying to help out. As he said in his debut episode, "I'm gonna float around for a little while...see where the current takes me." In a later episode, his new wife Mera explains his transformation: "Orin is finally embracing his destiny and leading his people." I can see the same thing happening in Wan's movie without contradicting anything.
I'm pretty sure what we're seeing is essentially what happened with the X-Men movies, in that some of the later installments went out of their way to ignore (or at least didn't care) what happened in the poorly-received installments like X-Men 3 or Wolverine: Origins. Even before Days of Future Past officially retconned everything, you had stuff like First Class flagrantly contradicting stuff established in those two movies, and nobody really cared.
What would have to be ignored, though? Tone seems to be a big issue, and there's no retconning that, and if it's just superficial changes of that sort that's not so much a soft reboot or retcon as an evolution based on the journeys the characters have already been on. That said, some character beats, like the tornado, killing Zod, brutal Batman, and the death of Superman I know people didn't like, but why would those things have come up naturally in subsequent films anyway? Perhaps if one wanted to include in one's film an alive Jonathan Kent or Zod, but why would you?
As long as they're good, nobody is gonna mind.
It may not hurt the movie's performance or even how someone feels about something overall, but I can't imagine
no one minding or
no online activity over it.
