One thing I find extremely odd - Throughout the "getting the gang together" phase of Supes V Bats and Justice League, it was made very obvious that WW had been hidden away since WW1 and hadn't done any WW stuff and yet here she is in 1984 with cameras everywhere, TV, Radio etc to record everything that goes on plus hundreds of actual witnesses, CCTV etc seeing her in the White House, running down the packed out crowded streets in full WW uniform and fighting in Malls etc and stopping a world changing "Avengers level" event that EVERYONE would remember yet apparently NO-ONE knows about this super-hero by the time we get to the later films??????
Unless there's some world wide "Men in Black" style memory wipe mcguffin involved in the final scenes, where everything resets to how it was before once the battle is over (which is a terrible screenwriting trope), then they've really backed themselves into a corner with continuity at DC.
