[[folder:The Novel]]
* FunnyAneurysmMoment: Among the souls encountered during the brief flight of the glider is a pilot of the Space Shuttle - who died, in Carpentier's future (it was written in 1976), when it suffered a failure of the heat shield, and well..."halfway down and going like a meteor when we got a burnthrough under the nose" took on terrifying truth in 2003.
* OneSceneWonder: [[spoiler: Lucifer, chewing legs like cigarettes makes eye contact:]]
--> [[spoiler: "Carpentier. What will you tell God when you see Him? Will you tell him that He could learn morality from Vlad the Impaler?"]]
* ValuesDissonance: The constant conflict between the strict Christian morals demonstrated in Hell and Carpent(i)er's modern, secular values (probably also those of the authors) lead him to conclude that GodIsEvil. However, the fact that most people nowadays are uncomfortable with the concept of infinite damnation for finite sins leads to a FamilyUnfriendlyAesop: [[spoiler: anyone in Hell can escape if they can get over themselves enough to seek redemption. Even if their punishment involves complete immobility or vigilant guards. Then again, there seem to be souls whose duty is to guide others, including Benny - and ultimately Carpenter himself]].
** Dante's ''Inferno'' was also based on older concepts. The sequel is post Vatican 2, and thus deals with it very differently in dealing with the values dissonance.
** The guards almost never stop anyone from going deeper into hell, as very few believe anything exists down there but worse punishments. And the sequel has Carpenter dealing with the people that are trapped and immobile, trying to prove to himself that his idea that anyone can leave is correct.
** The middle ring of the seventh circle is the Wood of Suicides in Dante's ''Inferno'', with a sideline in punishing the "violently wasteful" (profligate). Now, the wood is gone and the profligate are far more numerous. (Examples in StrawmanPolitical).

[[folder:The Film]]
* AdaptationDisplacement: Few fans of ''Film/{{Suspiria}}'' are aware that this is supposed to be a sequel (to be fair, the two films have little in common plotwise, other than the overarching mythology, which Suspiria makes almost no reference to). [[MotherOfTears The third film]] remedies this by directly referencing the plots of the previous two. However, fewer still are aware of the Thomas De Quincey poem, "Literature/LevanaAndOurLadiesOfSorrow", on which the mythology is based.
* AlternateCharacterInterpretation: [[spoiler: Mater Lachrymarum]] is heavily implied to be hypnotic and meddling in Mark's life while in Rome. How much of what follows is someone else's idea?
* AntiClimaxBoss: [[spoiler: Mater Tenebrarum, whose demise occurs due to an accident earlier in the film.]]
** NeverFoundTheBody, though. [[spoiler: Tenebrarum's death is far from clear, as she simply vanishes amid rising flames. She'd previously disappeared and reappeared in a mirror just a scene prior, and her transformation into Death presumably makes her more difficult to kill than Suspiriorum in the previous film.]]
* AwesomeMusic: The [[ theme]].
* EvilIsSexy: The mysterious woman in the music school [[spoiler: who WordOfGod later confirmed was Mater Lachrymarum.]]
** Perhaps not sexy, but Mater Tenebrarum is revealed to be especially pretty.
* {{Narm}}: "Help help, the rats are eating me!"
** The cat attack. The close-ups of the cats' mouths are more cute than scary.
* SpecialEffectsFailure: The cat scene as well as a few others.

[[folder:The Comic]]
* CrowningMomentOfFunny: One of the Spider-Man tie-in issues mentions that one of the side effects of the event is that the Daily Bugle's presses spontaneously started printing porn.
* IdiotPlot: ...So, nobody thought to check out Madelyne's DNA to see if it matched Jean's?
** Why didn't Sinister just use Cyclops and Jean's DNA to create the baby instead of going to such convoluted extremes? Made even worse because ''that's exactly what he does'' in the AlternateReality crossover, The ComicBook/AgeOfApocalypse.
** Chalk it up to being written in the 1980s before "CSI" made everyone an inexpert forensic scientist. DNA testing was advanced significantly in the 1990s, which coincides with its appearance in many crime shows.
* MoralEventHorizon: An attempt to kill a dozen innocent babies including your own infant son just has to count as this.
* NightmareFuel: Many instances, but particularly when Madelyne tries to kill her own baby.
* TheyWastedAPerfectlyGoodPlot: The demon [[TheChessmaster chessmaster]] N'Astirh is introduced, and killed, in this story arc. Given that he's just another magic-user, fans who think Belasco, the sorcerer who turned Illyana into Magik in the first place, should have returned for this instead consider his introduction to be this.

[[folder:The Game Mod]]
* BestLevelEver: "Nemesis", the penultimate mission in the original story, has been praised as one of the finest [[TheWarSequence Battle of Endor]] missions the community has ever produced.
* DemonicSpiders: The Vindhacyl bomber. Uniquely, it's only so because of how hard it makes any EscortMission. Inferno-issue super-painful bombs, a not-shabby beam cannon in a forward turret, and ridiculous amounts of shield HP make it nightmarish to fight in an interceptor because you just can't ''hurt'' the thing.
* OnlyTheAuthorCanSaveThemNow: What exactly humanity was supposed to do against something like the ''Gargant'' was never really answered. Whether the ''Gargant'' still exists is also up in the air.
* ThatOneLevel: "Nemesis" is also considered this by many, because of its sheer length (playthroughs can run as high as 25 or 30 minutes) and existing long prior to a practical "checkpoint" system like in Blue Planet to allow restarting from mid-mission.
