* AntiClimaxBoss: Helena Markos. [[spoiler: She's the head of the coven of witches who can do pretty much anything they want. Once Suzy sees a flaw in her invisibility, she easily stabs her]]. ''Film/MotherOfTears'' addresses this, saying that she had been left in a weakened state from a battle with another witch.
* BigLippedAlligatorMoment: The German slap-dancing scene. It serves no real purpose to the plot, and it completely interrupts the ominous atmosphere.
* CrowningMusicOfAwesome: The entire score by Goblin is pretty impressive, sometimes even entering HellIsThatNoise territory.
* EarWorm: The intro to the main theme.
* EnsembleDarkhorse:
** [[http://en.wikipedia.org/wiki/Albert_%28Suspiria%29 Albert]], the little boy, has gained an inexplicable cult following.
** Miss Tanner as well is one of the most memorable characters in the film, with many calling Alida Valli the real scene-stealer.
* FirstInstallmentWins: ''Suspiria'' is seen as a classic of horror cinema, despite some flaws, and it is widely respected in film circles. ''{{Film/Inferno}}'' is viewed as SoOkayItsAverage (though it does have a strong fanbase too) while ''Film/MotherOfTears'' is viewed as a disaster.
* {{Narm}}:
** "[[Literature/{{Beowulf}} So]]! You've come to kill Helena Markos! A ha ha ha!" Mostly all of Helena Markos' lines in the English dub are overly [[LargeHam hammy.]] Averted in the original Italian dub [[NightmareFuel 'I'm coming, American! And let the living meet the dead, and the dead the living...']]
** The first victim's name happens to be ''Pat Hingle''. It's either an unfortunate coincidence or one of the weirdest {{Shout Out}}s in the history of cinema. Knowing Argento, it's most likely a ShoutOut.
** Immediately after the blind piano player is fired, he goes to... well, the Cine-Masochist described it as a "German brodance festival", and that's the only term that fits.
** The "names of snakes" scene is odd to watch, mostly because it's bizarre to see girls in their twenties bickering like children. This is a leftover detail from the original script where they were children. Dario Argento just didn't change the lines.
* ParanoiaFuel: The witches can strike at any minute, killing whoever they want and MakeItLookLikeAnAccident (in the case of [[spoiler: Daniel]]). Or else they can just make it look as if someone ran away and vanished [[spoiler: like Sara]].
* {{Squick}}: Nothing like brushing [[spoiler: maggots out of your hair.]]
* SpecialEffectFailure: A bat attacks Suzy in the third act, but it looks incredibly fake.
* VindicatedByHistory: Although the film was a commercial success, it was trashed by critics upon release because of perceived plot holes and weak characterization. Nowadays, it's considered a masterpiece of SurrealHorror and one of the most visually stunning films of all time.
* VisualEffectsOfAwesome: The set design and lighting truly seems like something out of a nightmare.
