Iron Man 2, The Incredible Hulk, Captain America The First Avenger and Thor(2011) all struggled before it took off all SW needs is that one film I Think The High Republic maybe it The Way Avengers also The High Republic does have the Advantage

A) not being tied down by Legacy Characters

B) New Characters

C)Being set years into the Past
