I don’t agree. Part of it is my preferred comic book universe sensibility. If you’re going to do X movie from X Universe, you have to take the pains to include the trappings, or you might as well just pick a different name and and make a similar movie and not bother with the trappings of the source material.
Otherwise you just have every other self-contained genre property movie, which was fine at the time, but I’ve been waiting for linked superhero movies for years and now we have them and now Warners wants to go back to the old way, because they think they will regain Dark Knight glory.
I don’t think the market is going to react that way. I think they’re gong to spend more time explaining their balkanized properties rather than just giving a nod and a throw-away line or to to explain something and moving on with the story they want to tell.
