Of course, that delusion goes away immediately if you creep outside of the pages of Dark Knight Returns and read anything else that Miller has written with Superman. In the Miller world, every woman is a prostitute, whatever Batman says is immediately added to 1 Corinthians, and Superman is a mighty buffoon. You could lead him into a pit of lava if you put a sign that said "America Inside" in front of it. And he's wrong about everything. He can't be forced to grasp concepts more complex than "Fly directly into that tank" until Batman beats them into him. Batman is Miller's raging hard-on, something that he refuses to call his doctor about as he swings it through the fabric of the comics industry. Superman, on the other hand, is a Miller armpit fart.
"You ever hear the one about how Superman is, like, soooo dumb?" Pfbbbt. Pfbbbt. Pfbbbt.
"Yes, Frank," the party guests sigh. "Several times."
That's why the news of Frank Miller writing a Superman: Year One in 2017 causes such a deafening groan across the landscape of DC Comics. Because if most of his prior Superman work is any indication, it won't be nuanced and ceaselessly engaging like Batman: Year One; it will be a repeat of the same joke that Miller has been telling us for 20 years.
"Why did the chicken cross the road?" Miller asks.
"I don't know, Frank," you say as you head out the door. "Why?"
"Because Superman is, like, soooo dumb. HA HA HA." PFBBBT. PFBBBT. PFBBBT.
