Content: Check out the advantages of that  user story format. A Scrum epic is a large user story. There's no magic threshold at  which we call a particular story an epic. It just means "big user  story." I like to think of this in relation to movies. If I tell you a  particular movie was an "action-adventure movie" that tells you  something about the movie. There's probably some car chases, probably  some shooting, and so on. It tells you this even though there is no  universal definition that we've agreed to follow, and that an  action-adventure movie must contain at least three car chases, at  least 45 bullets must be shot, and …. So, "epic" is just a label we apply to a large story. Calling a story  an epic can sometimes convey additional meaning.
