She's ranking in presales WITH the other biggest MCU films: Infinity War & Black Panther.
Infinity War was a culmination BLOCKBUSTER every MCU fan was losing their minds over to see.
Black Panther proved to be an astounding cultural phenomenon that shattered quite a few expectations.
To have Captain Marvel ranking so high based on HYPE ??? That is an incredible achievement IMHO. I hope it proves as worthy as I want it to be.
