I believe this to be the case as well mostly, due to the fact that this film is likely, not only leaving clues to the overall meta storyline, but leading up to the second part of Infinity War.
I know A LOT of friends who will be watching this for the end credits for clues of IW... even if the end credits were attached to a turd of a movie.
Make no mistake... the movie will be entertaining but those that are low balling this movie is really isolating their guesses from the overall structure that Marvel has put in place. I respect their opinions, make no mistake, but in my opinion it's only looking at the movie as if there's no other appeal to the movie other than a new superhero.
