Not that DC Comics, now a part of Warner Brothers, does not have interesting properties. It just that their great heroes of old aren’t as appealing as those from Marvel’s minds. Sure, Batman is the best one, and Superman has carved his niche, but Aquaman? News is there’s a Wonder Woman movie in the works, and people are developing storylines for Flash and Shazam.
But my point from the title is that people identify more with regular guys thrust into extraordinary circumstances than they do with gods and aliens defending the world from other gods and aliens.
