We all saw the list, and we all know what was NOT listed through 2019 so far. A new standalone iron man movie.
Most people liked the first a great deal, but the following two installments, while wildly successful financially, were creative duds by an awful lot of people. They are the X-Men Last Stands of the series. RDJ seemed to have his agents/lawyers put an awful lot of effort into increasing his presence in the new captain america movie, over and above the appearance in the avengers movies.
What this suggests to me, is that even people like RDJ knows that his standalone movies were creatively bankrupt compared to winter soldier and gotg. He did not clamor to get into a new thor movie, because even those are not as fertile for rich content like captain america was/is.
Thoughts?
EDIT:
PS
I am not against iron man, his first movie was excellent, and I think he is FANTASTIC as part of a larger ensemble where the focus is not just on his own particular comic universe.
