I'm glad that they didn't just do the same type of story three times. That would make for a boring trilogy. They managed to keep it interesting and touch on all aspects of Cap's story (WW2, solo hero and Avenger) by telling different types of stories in each movie. And despite it's extended cast, Civil War was definitely and distinctly a Captain America movie. The story revolved around Steve and his choices, it featured his supporting characters and wrapped up his story arcs and the story arcs of his supporting players as well his time as wielding the shield.
