I picked up my first comic books in 1990. There was an Amazing Spider-Man drawn by future Savage Dragon creator Erik Larsen; an issue of Detective Comics written by one of my favorite comics writers, John Ostrander; and an issue of Avengers written by Larry Hama and drawn by Paul Ryan. The story in question there would introduce such classic Avengers foes as the Tetrarchs of Entropy and a hallucinating Russian cosmonaut called Surge, but only on the cover of the next issue.
Never heard of them? Never mind that. We also got Rage. He stuck around for a while.
Fans of the Marvel Cinematic Universe were fairly excited to learn the third Captain America movie would be an adaptation of Civil War, a mini-series where the various Marvel heroes lined up on two sides over a law that required superheroes to register with the American government or go to prison. The series dealt with issues regarding national security and the American reaction to terrorist attacks on our soil.
It also had some huge problems that almost guarantee the movie version will be better, if only by default.
