You could just wait for the new Captain America: Civil War movie to come out in May, but if you’re the kind of person who likes to do comic book research before you watch your comic book movie, then this video is for you.

It’s a perfect, concise version of the events that went down in the comic version of Civil War, which was a highly complex series of comics, that spanned over multiple titles, and included the deaths of several key superheroes. Although this video is talking about the comics, it could potentially be spoiling parts of the upcoming movie. So consider yourself warned.
