* {{Anvilicious}}: The series is not exactly subtle in its themes, metaphors and particularly religious symbolism.
** SomeAnvilsNeedToBeDropped: Proponents of the series believe that the things it's saying needed to be said.
* AwesomeArt: Done by the ''incomparable'' Alex Ross working at his fullest and finest.
* BadassDecay:
** Poor Lobo, getting on in years, has gone from the Main Man to the Main Homer Simpson Lookalike.
** ComicBook/MartianManhunter gets it even worse than Lobo, from a guy who could clash with Superman reduced to a nervous wreck who can barely control his body.[[note]]One might argue that since he is still trying to help humanity despite a complete breakdown of his powers makes him ''more'' badass.[[/note]]
* EnsembleDarkhorse:
** '''[[BadassPreacher NORMAN]] [[GoodShepherd MCCAY.]]''' It is a damn ''crime'' that he's never appeared in the main continuity.
** Boston Brand's (Deadman) four page cameo. He's even wittier in the {{novelization}}.
** Magog ended up becoming this for the writers; they initially made him a cliched representation of everything they hated about NinetiesAntiHero and [[UsefulNotes/TheDarkAgeOfComicBooks the culture he represented]], but he gained unexpected depth through the writing of the series until he ended up being one of their favorite characters from it. Sadly, when he was [[CanonImmigrant brought into the main universe]], he went in [[TheScrappy the other direction]].
** Nightstar due to being a walking representation of the marriage between fan-favorite coupling Nightwing and Starfire, and being [[MsFanservice very easy on the eyes]] besides.
** Kid Flash (Iris West, Wally's daughter) is also quite popular and has made frequent appearances in the regular DC Universe long before Superman did.
** Red Hood is quite popular too. She's essentially the grown-up version of (fan favorite in her own right) Lian Harper, her persona being a blend of her dad's Red Arrow self and Little Red Riding Hood.
* FranchiseOriginalSin: ''Kingdom Come'' inadvertently started the trend of pairing Superman and Wonder Woman in [[AlternateUniverse Elseworld comics]] [[note]]''The Dark Knight Strikes Again, Superman: Distant Fires, Superman: Red Son, JLA: Act of God, Injustice''[[/note]] before finally becoming a canon OfficialCouple in the ''ComicBook/New52''. However, while ''Kingdom Come'' devotes a great deal of time and attention to examining their relationship and crafting believable circumstances to bring them together, many modern comics just take it as a granted that the strongest man and woman will be attracted to one another, or simply write the romance poorly. One thing ''Kingdom'' does that few other stories do is [[PosthumousCharacter eliminating Lois Lane from the equation]] but also strikes the tricky balance of making sure that her presence [[TheLostLenore is still keenly felt.]]
** In addition, Diana had used lethal force in stories prior to ''Kingdom Come'', but it was always as a last resort. Some stories afterwards would depict her as a BloodKnight who preferred to kill first, ask question later, the ComicBook/New52 being the biggest offender of this.
* HarsherInHindsight:
** Hoo boy, the {{Novelization}} has Mera mentioning rumors Arthur and Diane were going to have a royal wedding to unite Themiscrya and Atlantis. Cue ''Comicbook/{{Flashpoint}}''. Yeah.
** Superman came ''that close'' to becoming [[ComicBook/{{Irredeemable}} Plutonian]].
** Seeing Ted Kord alive and well in this book stings pretty hard considering his treatment in the main continuity. [[spoiler:Until he's seen as one of the many fatalities of the bomb.]]
** Likewise, knowing Lian Harper is alive and a hero like her father considering the events of ''ComicBook/JusticeLeagueCryForJustice''. It becomes even harsher in the novelisation, where the entire Arrow family are killed off by the nuke.
** Also Billy Batson's BrainwashedAndCrazy became much more heartbreaking after the same fate that happened to Mary Marvel in ''ComicBook/CountdownToFinalCrisis'' and later Billy Batson in ''ComicBook/JusticeSocietyOfAmerica''.
** Norman [=McCay=]'s final line to Jim Corrigan is that it is nice to be remembered, if only in a silly way. [=McCay=] himself was not present in the book's sequel and has been used extremely sparringly since the end of the mini. Seems he was not so fortunate.
** Um...
-->'''Americommando''': This is ''MY'' country! For years, the Americommando and his Minutemen have protected the U.S. from foreign threats... only to have overlooked the most insidious menace of all! The poor, tired, huddled masses camping on our shores, begging citizenship! You immigrants dare expect sanctuary? (...) We can't house you now! We can't even feed you now! But still you force yourselves upon us! Well, no more! Today, the Americommando declares war on the wretched refuse! (...) My Minutemen will cleanse America's shores!
** Much like, well, everything about Americommando, Swastika's existence feels uncomfortably accurate following the rise of openly Neo-Nazi [[RightWingMilitiaFanatic fanatics]] in the 2010s...
* HilariousInHindsight:
** Deadman's appearance in this series: he is reduced to his skeleton in his uniform. Now take a look at what his [[ComicBook/BlackestNight Black Lantern self]] looks like...
** Selina Kyle has become wealthy thanks to a massive cosmetics empire - the profession of the BigBad in the later ''Film/{{Catwoman}}'' film.
** The notion of Bruce Wayne and Talia Al-Ghul having a child was apparently too tantalizing a storyline for the DC Comics writers to keep in the Elseworlds continuity.
** One of the bar scenes features [[ComicBook/{{Watchmen}} Rorschach]] talking to The Question many years before [[spoiler: ''ComicBook/DCRebirth'' made ''Watchmen'' and DC characters interacting a reality. Not in an Elseworlds novel, but in the ''main continuity!'']]
* {{Narm}}:
** One of the younger heroes likens Superman's invitation to work with him and the Justice League to being called as the Thirteenth Apostle.
** Captain Marvel's arrival at the Gulag battle is an OhCrap moment that's framed as a single-page SplashPanel. But the framing makes it look like Superman is looking at his crotch which has a noticeable bulge. And right next to the bulge is the narration box "Armageddon has arrived".
* OneTrueThreesome: Superman/Wonder Woman/Batman, in classic DC fashion. Notable in that [[spoiler: it's almost canonized. Batman is made the godfather of Bruce and Diana's child at the end, effectively making the baby a literal child of the Trinity.]]
* RescuedFromTheScrappyHeap: The entire [[UsefulNotes/TheSilverAgeOfComicBooks Silver Age]] generation of heroes.
* SomeAnvilsNeedToBeDropped: Americommando's racist speech about immigrants infecting the country and having the gall to expect refuge came across as incredibly over-the-top and [[{{Anvilicious}} heavy-handed]]...in 1996, that is. Nowadays, it comes across less as ridiculous and more as [[ValuesResonance disturbingly prescient]] callout of vile fascist ideology.
* {{Sequelitis}}: ''Kingdom Come'' was followed by ''The Kingdom'', which was... underwhelming.
* StrawmanHasAPoint:
** At one point, one of the "newbloods" calls out Superman to argue against the notion that they have saved lives thanks to their willingness to kill the most dangerous supervillains. While the new "heroes" are clearly reprehensible and vile, the reader is almost certain to find themselves agreeing there are some criminals who should be taken down permanently, rather than being given [[JokerImmunity relatively light sentences]].
** Considering that the Joker is an unrepentant mass-murderer that both the system and the 'classic' superheroes haven't dealt with yet, is it any surprise that the Magog's killing him is supported? The {{novelization}} goes into a bit more detail, explaining that Comicbook/LoisLane had sacrificed herself to give Superman the opening he needed to arrest The Joker, and as such Magog killing him made Lois' death completely pointless.
* ToughActToFollow: Creator/AlexRoss' style is viewed as incomparable by Creator/WarnerBros, which is why they do not plan on adapting it to animation.
* UncannyValley: Captain Marvel looks...off. His traditional features (EyesAlwaysClosed, PerpetualSmiler) look unnatural in the comic's photorealistic painted style. [[spoiler:Helpful of course because he is, after all, working with the villains.]]
-->'''Superman:''' Marvel! In the name of heaven - wipe that empty smile off your face!
* TheWoobie: Captain Marvel; a scared little orphan boy suffering from PTSD only to be taken advantage of in his vulnerability by Lex Luthor, enslaved into adulthood by bugs inside his brain only to die for the future of his people when he gains his freedom.
