Ignorance can be remedied. Stupidity is incurable.
We'll see. There is a such thing as diminishing returns. We may see more characters in an even bigger and crazier battle, but that still doesn't mean it will come off better than what we saw in Endgame. It's not really just about the size of the spectacle. It's also the fact that we had never seen anything like that before.
I never mentioned size. I mentioned those characters because they are part of some of the biggest stories in Marvel. And with those stories and players, it's easy to see them topping the end of Endgame.
