The Modern Age is the current age, the one we're in right now (we're talking about comic books, here). Ages don't get named until they're gone, so the present age is always Modern; thus, in five to ten years, we'll probably have to change the name of this entry. Both Dark Age and Modern Age influences can be seen in recent superhero movies. If The Dark Knight Saga is a Dark Age movie, then the Iron Man movies can be considered Modern Age movies.
