I'm not talking about what's in movies, though I would say none of the movies you listed actually do what I am talking about, that is, explicitly express the positivity of the Pax Americana and uphold the underlying philosophical and ideological values that built it, rather, those are simply movies that cheerlead the US military in the abstract. And the new Star Trek movies? Dude, none of those uphold the ideals of the Pax Americana and in point of fact "Into Darkness" is explicitly written as a criticism of American ideals with considerable influence of a 9/11 Truther.
The ideals underlying Pax Americana are not about American militarism and imperialism, they are about the things that make America and Americans see themselves as the "good guys" on the international stage. The things that make Americans see wrongs in other countries and go "we should help". It is also the things that make Americans value free market economics, value a representative republic, and understand the value of civic duty and responsibilities.
Meanwhile you see dozens of Hollywood movies that explicitly create criticisms of the American system and American culture. From the constant portrayal of American Christians in villainous roles, to the near universal narrative of "corporations evil", to the constant portrayal of things like nuclear power as dangerous, the constant attacks on America's founding we see via so-called academics via "The People's History of the United States" (one of the most successful bits of propaganda ever passed off as accurate history) and now with the 1619 Project.
These processes have over the year degraded the morale and moral fortitude of Americans to the point where we are now, with a lack of moral clarity, a lack of leadership, and a sharp division between those who still hold to American values and those who would see the US fundamentally transformed into a socialist autocracy.
