I totally understand the "point" that it was no-win solution, but I think it's really incorrect to say the run was -not- about Steve and Tony. It totally was. It's fair to say Secret Wars isn't, and is it's own thing. I can respect that and enjoy Secret Wars for what it is - a huge send-off for Hickman's half-decade plus at Marvel and a celebration of the Marvel universe itself with Doom and Reed at the center of conflict. But the entire Avengers run? It was clearly about Steve and Tony, and the Avengers machine. That all amounted to nothing. And sure, you can say that was "the point" but I think the point could have played out in a more elegant way.
As such, it feels like the entire run was hyping up this huge "legendary" thing, which never happened. Maybe -that- is the point I'm failing to understand here. In the very first issue, the framework was made clear right at the start:
"Some say it began when Hyperion was pulled from another universe." <- Hyperion
"Some say it was when the guard was broken on a dead moon," <- Smasher
"Some say it was when Ex-Nihilo terraformed Mars into a green planet." <- Captain Universe/Ex-Nihilo/Abyss
"They were all wrong."
"It started before the light." <- The Last White Event
"Before the war." <- Infinity
"Before the fall." <- Time Runs Out? Secret Wars?
"It started with two men." <- Steve and Tony
"It started with an idea." <- The Avengers Machine
So from the start of the run, Hickman basically foreshadowed everything. He laid out his plans that he was going to tell a number of stories about escalation, about a lot of stuff happening, about the new Avengers characters he was creating having a role in these, and how some people would look back and think they were more important than they were. But in the end, it was all rooted in Steve and Tony having the idea to create the Avengers Machine. It would bring everyone together and it is even shown in possible futures that this idea outlives them both and becomes all consuming - taking over the universe itself.
But... leading into Secret Wars, all this is just... wiped away. So if none of this matters in Secret Wars in the end, the question is... what was the legend itself that "grew in the telling" and who are all the people who would be left around wondering where it all really began? Like I said, I would happily take it all back if the conclusion of Secret Wars ties back to all of this and closes the narrative loop, but as it is, I feel that the story did not end. If it was just Steve and Tony fist fighting as the world ends, there is no legend, there is nothing to speculate about, no one would be talking about it in the future or wondering how it all started, even if Battleworld ends and everything is put back together. No one would give a -fuck-. That's my point.
