I don't envy a script writer for a Marvel movie. I honestly cannot imagine the pressure of writing a story that has to not only stand on its own as a solid movie, but must also fit in with an increasingly interconnected universe that has Asgardian gods, giant green behemoths, and men flying in their own personal armor suits. Also, it not only has to appease people who have never picked up a comic book in their lives (or haven't read one in years) and people who still follow the story lines on a weekly basis.
With that in mind, I feel that Captain America: The Winter Soldier somehow managed to be both one of Marvel's best works at constructing a story that fits in the universe it lives in as well as one of the stories that also feels the most restricted by being based in a comic book universe. I'll explain further.
