Mahnke and Gleason taking turns, Gleason on the first issue at least.
Pencils were okay, but the inker really dropped the ball here. Gleason is still gonna wildly outshine Mahnke, but this issue wasn't really representative.
Plus, I don't really feel like it had pacing issues? Of all of them, actually, it was easily the best paced. GA worked pretty well, GL was basically entirely setup, but still worked for what it was, and Batman... well, Batman was really abrupt. I'll give you that
I guess I'm just not quite reconciling the people who are curious enough about extraneous details to ask questions like "where exactly did this other Superman come from" and not curious enough to actually find that out
We are told how young Superman died, btw. That's laid out fairly well in the issue.
I will say, "old Superman and young Superman" being tough to follow does make sense to me as an objection; new comics readers aren't going to be able to roll with that kind of silliness right off the bat. But it's ultimately a "who pumps the Batmobile's tires" sort of issue. You've just got to swallow it if you're going to be able to enjoy the stories that are being told, and are going to be told in the future. Not much DC could do to fix that.
