^ If it embraces the fantastic, then by definition, it can't be the 'normal world.'
Which is exactly why the audiences hates the fantastic and demands that all Superhero movies have the "super" drained right out of them. They loath the idea of a superhero that exists in the modern world.
It's easy, have a Superhero movie that doesn't shy away from the wonder of Superheroes and have said movie be set in the modern day, it's a flop before it hits the screen.
Have a movie where the hero had everything super about them stripped away, and make it some minimalist "drama" about him fighting a gang of car thieves and the movie's a hit.
