To me it´s really more about what they´ve been showing. While posting a lot of tv spots they haven´t really revealed that much imo. Especially compared to Ant-Man 3, MoM and Wakanda Forever. I would love to see more about the villain and also more stuff like the first clip that is more fun like the Vol 2 trailer I posted. But that´s more for me personally then to improve sales, that will be as you say reaction/reviews (Hopefully).
