Enough superhero movies have been released that it’s no longer enough to tell a simple “save the world” kind of story.
The chances of them succeeding improve when they bring something new to the table, and Aquaman will do just that.
Beyond how it will learn from its DCEU predecessors, let’s also not forget that Aquaman will offer something that no other superhero movie has yet: an underwater setting.
Considering how ridiculed that hero has been for years, that would be one hell of an achievement.
