As for the journalism angle. You think Kevin Feige wouldn't be able to make a billion dollars by grafting All the President's Men onto President Lex with Lois & Clark in the Woodward and Bernstein roles and some crazy selling earth to Brainiac scheme ala Morrison in place of Nixon & Watergate? Of course they would. That's the Marvel formula. Take their properties and fit them into existing movie genres outside of your standard superhero movies. Winter Soldier already did the '70's political thriller.
