Ever since Avengers: Endgame was released, many fans have been moaning about ‘plot holes’ in the movie. Most of these are inevitable in a movie that features time travel, some of them are little quibbles addressed directly in the movie itself, but some are actually good points that appear to have been thought of in advance by the directors. Since the film’s release Joe and Anthony Russo have been opening up on the titanic effort it took to make Infinity War and Endgame, and (no doubt relieved that they can finally openly discuss the plot) have started to address some of these fan questions.
