Dark Knight III: The Master Race issue number 1 written by Frank Miller and Brian Azarello has yet to be released on November 25. But the reviews are out, so consider this as a warning of the spoilers below.
The writers has set the first issue of the comic in a futuristic Dark Knight universe but it very much resembles the world we live in today. The conflicts are very much relatable, like for example, Batman fighting cops, to the defense of innocent African American young men being targeted for murder.
A notable detail in the issue is how it shows female characters Ellen Yindel, Carrie Kelley, Wonder Woman, Lara Kent, all dealing with their own battles, with the strong desire to leave their own mark. Wonder Woman and Lara are shown to be brawny and Carrie is not Batwoman or Batgirl, but the Batman.
"I just think the suit looks a lot better on a girl," Dark Knight creator Frank Miller jokingly remarked to the New York Post.
According to IGN, in terms of the illustrations, the artists did a good job in capturing the darkness of Miller's universe and infusing it with their own creativity. It should be noted that they have masterfully included Miller's signature blood splatter, but the way they depicted characters like Ellen and Carrie without their usual costumes makes them worthy of illustrating the comic series.
Most comic reviewers regard 'The Master Race' first issue as a success for the team that made it. The story gives nostalgia to its readers as it has the feel of 'The Dark Knight Returns' but the characters are placed in a modernized setting. The art is loyal to Miller but the artists did tweak some aspects depending on relevance and necessity. It would probably meet your 'darkest' expectations because it would build anticipation for the story it would soon reveal.
