When I said Ant-Man 2 numbers, I did not mean to say it would do exactly the same, but in the same ballpark. Also, you said you don't see it going under 250M domestic and my prediction was 270M so within the range you believe is possible to do domestic.
I am not saying it doing in the 600M range is the "right" scenario or anything, It's just my prediction given the worse state of the MCU now compared to 2019, no Endgame hype to boost it considerably, China contributing with probably around 100M less, overall decline in overseas markets and (this is a very important part of my prediction) the fact that I personally think the movie will not have a good reception.
