* AluminumChristmasTrees: The idea of what some reviews referred to as a “magical t-shirt” might seem odd, but were [[https://www.metmuseum.org/art/collection/search/453498 not at all unheard of in the medieval period.]]
* AntiClimaxBoss: [[spoiler:As has become the norm for this trilogy, Mater Lachrymarum is killed rather quickly.]]
* CompleteMonster: [[WickedWitch Mater Lachrymarum]], the [[OneBadMother Mother of Tears]], is the most beautiful and powerful of her wicked sisters. Upon awakening from her deep slumber, Lachrymarum disregards the deaths of her sisters and proceeds to unleash a wave of violence onto Rome ranging from random acts of vandalism, to possessed mothers [[OffingTheOffspring killing their own babies]], to mass suicides. Lachrymarum also saw her devoted followers as expendable, allowing them to [[ImAHumanitarian cannibalize]] and torture each other as they saw fit to her cruel amusement. Lachrymarum's ultimate goal was to usher in a new era of witchcraft starting with the obliteration of Rome; with victory seemingly within reach, Lachrymarum attempts to offer the heroine Sarah Mandy, daughter of the one good witch who had managed to once fight the Three Mothers, to her cannibalistic followers. Seeking to expand her powers until she blighted the world itself in darkness, Lachrymarum demonstrates the pure, unbridled evil of the Three Mothers.
* {{Narm}}: The monkey. It looks like shit.
* {{Sequelitis}}: Critics and many of Argento's fans thought it was a disappointing third chapter of the trilogy.
* SoOkayItsAverage: It has some defenders. They admitted that it is flawed, but still remained entertaining.
* SpecialEffectsFailure: The scene where a mother walks with her baby in her arms to the edge of a bridge and drops him would've been terrifying... except the falling baby is clearly a puppet.
* TheyChangedItNowItSucks: Argento took most of what made ''Film/Suspiria1977'' and ''Film/Inferno1980'' great and discarded them in favor of a more open environment and violence for the sake of violence. This doesn't fare well for ''Mother of Tears.''
