And you acting like it's
"mandatory" that they cross-pollinate each other's movies.
Which IT IS NOT.
Lemme help you out...
Iron Man is an Avenger.
How many other Avengers have appeared in Iron Man's 3 SOLO movies?
The only Avenger who ever made a cameo was...
War Machine (aka Rhodey).
Thor is an Avenger.
How many other Avengers have appeared in Thor's 4 SOLO movies?
The only Avenger who made a cameo was...
The Hulk.
Ant-Man is an Avenger.
How many other Avengers appeared in Ant-Man's 2 SOLO movies?
The only Avenger who made a cameo was...
The Falcon.
Black Widow is an Avenger.
How many other Avengers appeared in her SOLO movie?
The only Avenger who made a cameo was...
NOBODY.
Black Panther is an Avenger.
How many other Avengers appeared in 2 Black Panther SOLO movies?
The only Avenger who made a cameo was...
Bucky.
The reality is.. there has only been ONE SINGLE... "SOLO MOVIE".... in which a lot of other Avengers have appeared - and that was in
Captain America: Civil War, back in 2016.
So aside from this ONE SINGLE SOLO MOVIE... Ummm... where else does all this "cross-pollination" happen, that you speak of? Hmm? Do tell.
If you are referring to the habit of ONE SINGLE other Avenger character making a... quick cameo... in someone else's solo movie... then the 1st Black Panther movie has already filled "the quota" of Avenger quick cameos that the other MCU Solo movies have had.
So what's the problem?
They are not ENTITLED to appear in each other's movies... It's not MANDATORY.
Yet somehow, you have some misplaced
EXPECTATION that they are....... SUPPOSED TO........ appear in each other's SOLO movies.
Read the
biggest words on the Movie Posters: It's called
"Wakanda Forever".
Nobody else on the Avenger's roster is OWED a "quick cameo", in this movie.
Let that sink in.
Stop bitching.
