That's going to wind up being a tough one.
It feels like even John/Jane Public are probably at least partially aware that this is the end of the line for the continuity of this "Era" of the IP.
Knowing that, it's not like there is the same investment as something like Avengers: Infinity War.
Never mind that there is the whole "Fans With An Issue With Mystique's Position In This Continuity..." group of folks.
Just lots of stuff working against it with nothing that's seemingly stellar working in it's favor. It's not even like there is a bit of hype around a Quicksilver showcase section in this film. If it's there, they aren't making much of it.
