And yet, people instead embraced the grimdark approach as "cool", and over the coming decade, proceeded to push (or encourage, if we're talking about readers and their money) mainstream superhero universes into a format that would sometimes make TDKR seem tame in comparison. When Mark Waid rewrote TDKR as Kingdom Come (if you'll allow the lineage), the same approach was now a critique of what mainstream comics had become, as opposed to an original contrast. But the same thing happened. It merely reinforced the readers' love of grimdark. What's wrong with us? Similarly, Frank Miller's All-Star Batman & Robin, in many ways the ultimate example of grimdarkery - and referenced because it features a Jimmy Olsen working at the Gotham Gazette who may well be a younger Olsen-31 - could and probably should be read as a critique of the subgenre/style, or at least a hyperbolic spoof of it (which is a form of criticism). It's all right there in that speech.
James Olsen-31's Greatest Hits:

*The article "Truth to Power", which evokes the speech above (TDKR #2)
*Reveals the President is a hologram (The Dark Knight Strikes Again #1)
*Killed by Luthor and BrainIAC when Metropolis is destroyed (TDKSA #3)
