Marvel Studios has clearly made a point that rumors of its jaded, decrepit demise being imminent, may have been exaggerated, because it is hard to believe that anyone capable of having millions of people enthralled by a row of chairs is in some kind of death throe. However, Captain America: Brave New World’s lackluster box office – in Marvel terms – was a little bit worrying for the future of non-Avengers movies. But perhaps the franchise’s newest group of somewhat dubious heroes could be about to come and save the day.
