Wow, you must be dizzy from all this spinning. Your original point wasn't exclusively about commerce (e.g. "It set up all these dark and surreal pieces only to then for WB to not follow up on any of it in their subsequent films"). You were talking about the narrative follow up of character arcs. I provided direct citations from the films (BvS's ending, Suicide Squad, Justice League) to support my analysis.
I didn't just mention Justice League, though. I cited BvS and SS too. Justice League has a combination of approaches from different storytellers. I can judge the parts that I know were Snyder's and from what I know of Snyder's intentions. Still, it has to be acknowledged that the narrative process was interfered with after the fact. Meaning, you can't criticize BvS and Snyder for its storytelling when, during its original crafting, it was thought that JL would expand on certain things. As for the commercial angle, BvS wasn't a total flop, and JL was affected by its own bad press from reshoots and it just being a poor film that alienated even the existing DCEU fans.
So what? You were complaining about the Easter Eggs that are totally irrelevant to all of this. They're just something extra to enjoy or not enjoy as anyone so chooses. They don't affect plot or pace, and no one is saying that their existence means the film should be liked more or should have made more money. Let me put it this way. Snyder and his fans have been having fun discussing things they love and are interested in. It's like he's a professor who offered a course on a subject and interested students are registering and attending his lectures. People like you are like people who major in other subjects or elected not to take the course for whatever reason, yet you can't help interrupting our discussions to piss in people's cornflakes. You, and others like you, are turning their little hobby into something that's it's not just to beat the dead horse of your dislike for these films. It's petty.
