All the reactors i seen online are liking/loving this trailer,so mcu fans,audiences etc.. are liking/loving it.
One of the reasons it looks different then other mcu movies and second most folks do not know anything or very little about them and folks are liking/loving the music and folks are exciting to see the cast,story,costumes,the way it looks and powers, so some here who are not liking it,meh on it etc.. are the small minority.
All mcu films are different from each other by the way.
Anyway this was really good trailer and exciting one.
