Superhero films have managed to prove they're here to stay from a box office standpoint, though there will always be naysayers who predict a bubble pop of some point on the genre. While there will be ebbs and flows of popularity, it is the same across every genre. Regardless of your stance, any scaling back on the genre won't be because of a lack of stories to tell.
Wonder Woman director Patty Jenkins was asked about "superhero fatigue" during a panel at WonderCon (via Cinema Blend). She said "That's the great thing about the diversity of superheroes, and one of the reasons why when people say 'Is the superhero thing gonna die?' or whatever, I always think it's so much bigger than that. It's not about superheroes. It's about the method of universal storytelling that all people have that is not of one religion, one thing, that America ended up inventing as a way to tell these metaphors about all different kinds of states of being. So to me, they're the same as the Greek myth, they're the same as the Roman myth, or religious figures of every religion. These are our common characters that we use to express stories about being a better person, or what you would do if you were faced with various things. So for me, that's an incredibly powerful thing. There's a million movies to be told with [these] common characters."
The argument of superhero fatigue hasn't resonated with many because these heroes have already lasted for over 60 years in most cases, so they have already proven they are lasting aspects of popular culture. There will always be new stories to tell, and a variety of ways to do so.
Wonder Woman hits movie theaters around the world next summer when Gal Gadot returns as the title character in the epic action-adventure from director Patty Jenkins. Before she was Wonder Woman, she was Diana, princess of the Amazons, trained to be an unconquerable warrior. Raised on a sheltered island paradise, when an American pilot crashes on their shores and tells of a massive conflict raging in the outside world, Diana leaves her home, convinced she can stop the threat. Fighting alongside man in a war to end all wars, Diana will discover her full powers…and her true destiny.
