As it turns out, that trailer may have told us even less about the movie than we previously thought.
Even certain parts of Infinity War had to be shared in the marketing to get people on board.
Remember that recently released Avengers: Endgame trailer that hardly showed us anything about the movie but still managed to get the entire fanbase unreasonably excited?
It so profoundly moved me because I didn’t know a damn thing about the story I was going to watch.
