The stand-alone story about the Superman of Earth 23.
Okay, so on Earth 23, Superman's a black guy, and is also President of the United States. While his secret identity is 'Calvin Ellis,' it's implied that this Superman is basically a stand-in for Barack Obama. And Lex Luthor has to vociferously defend his enmity toward Superman by yelling "I'm not racist! It's everything else about you that I hate!" Now, I'm not going to go on a big lengthy political diatribe here, because I don't wanna make a big 'thing' out of it, but..........come on, really? I mean, it's admittedly not a very deep parallel since they don't bring up policy or anything other than "he's the President and he's black," but it's still there, and IMO it's meant to bait people into an argument over it.
Under Superman's administration, everything is awesome, and even when he's solving problems in-costume, he has a robotic double (controlled by Brainiac) handle crises as President. So yeah, Superman is in a position of essentially supreme power, with a cowed and obedient Brainiac as his servant.
Where have I seen this before?
We've seen stories with Superman or a Superman-like figure in positions of total authority before, and it's always shown that
that's a bad thing, that even the best man is prone to the corrupting of absolute power, and that even a well-meaning tyrant is still a tyrant. Here, though, it's celebrated, and a universe-hopping Lois Lane goes so far as to call him "Superman done right," basically stating that seizing power under false pretenses (his identity as Superman is still a secret), running a powerful shadow-government (since he has Brainiac running the show in secret), and using the Justice League to flat-out invade other countries (they're shown flying into Qurac and destroying their nuclear program) is perfectly okay--and not just okay, but ideal--as long as he's "on our side." At least Wonder Woman points out how hypocritical they're being, but still willingly goes along with it anyway. Who Watches The Watchmen, indeed.
Maybe it's just the rabid Libertarian in me, but I find that whole concept incredibly disturbing.
However, once I get past that (which isn't easy), there's another part of this comic that I thought was actually really clever. There's a parallel-universe version of Lois Lane, Jimmy Olsen, and Clark Kent who are traveling from universe to universe to escape their world's version of Superman, who was created by a thought-powered doohickey to be the peak of human ideals, but then was twisted into an evil and violent mockery of itself by their corporate backers to be more 'marketable.'
This was a pretty entertaining deconstruction of the typical "Superman needs to be dark and gritty" bitching about how they should tone down the character's idealism to make him more relatable and cool, and how doing so betrays everything that the character is meant to represent. Of course, they kind of overdid it by then making that Superman a big 90s robot-thing and having his symbol resemble a Swastika, but it was still a rather neat idea.
