Inferno (1980 film)/YMMV

• Adaptation Displacement: Few fans of 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). 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, Levana and Our Ladies of Sorrow, on which the mythology is based.
• Alternate Character Interpretation: 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?
• Anticlimax Boss: Mater Tenebrarum, whose demise occurs due to an accident earlier in the film.
  • Never Found the Body, though. 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.
• Evil Is Sexy: The mysterious woman in the music school who Word of God later confirmed was Mater Lachrymarum.
• Special Effects Failure: The cat scene as well as a few others.
