YMMV / Cthulhu Mythos

  • Broken Base: Almost all of the works in the Cthulhu Mythos that weren't originally written by H.P. Lovecraft count for this.
  • Complete Monster: Nyarlathotep differs from most of H.P. Lovecraft's gods. While Lovecraft describes other Outer Gods and Great Old Ones as mindless or unfathomable, Nyarlathotep is a sadist who is fully aware of humanity's existence, and enjoys exercising his power over them. He kills or drives people to madness while disguised as the Haunter in the Dark, drives entire societies to ruin in the form of the Black Man or the Black Pharoah, and generally treats all life as part of some giant cat-and-mouse game.
  • Creepy Awesome: Any and all of the gods.
  • Ensemble Darkhorse: Cthulhu has so little role in Lovecraft's work, yet is the most famous now.
    • Despite showing up in about two Mythos stories, Cthylla is pretty well known.
    • Nyarly is this for being one of the only truly evil beings in the Mythos.
  • Everyone Is Jesus in Purgatory: Interpreting the end of The Dunwich Horror to be a parody of the Crucifixion.
    • Until you re-read it, and realize that it undoubtedly IS a parody of the Crucifixion...
  • Fanon: A lot of the "mythos" could be considered this, since so much was built up by later authors, rather than Lovecraft and his contemporaries. Of particular note is the belief that "Dagon" is a Lovecraftian God and a servant of Cthulhu. Pretty much any reference Lovecraft makes to "Dagon" in his own stories could be read as in-universe mythological allusions, out-of-universe mythological allusions, or a code name used by Cthulhu worshippers to avoid attracting attention.
  • Fanon Discontinuity: While there are plenty of canon disputes within the fandom, Bloch's "Shadow From the Steeple" is commonly held in low regard.
  • Fandom Berserk Button: In an odd inversion of this, "misspelling" a Great Old One's name in a fan work is actually a handy way of showing off your knowledge of the Mythos, since it complies with Lovecraft's reminder that there is no definitive way of spelling the Old Ones' unpronounceable names in any human language. Alan Moore's The League of Extraordinary Gentlemen, for example, frequently references the Mythos, but it always spells the eponymous character's name as "Ktulu".
  • Go-Karting with Bowser: Parodies tend to have Cthugha and Nyarlathotep (mortal enemies in the main mythos) as friends or trying to pair them up.
  • Hilarious in Hindsight: Lovecraft described Azathoth as a monstrous indescribable thing which resides in the center of the universe, often described as "gnawing" and "chaotic". Scientists now believe that the center of our galaxy (and, by extension, other galaxies), is a supermassive black hole. Perhaps Lovecraft was on to something...
  • Inferred Holocaust: The bodies most commonly associated with the Yithians? Those belonged to beings native to Earth before the Yithians used their mind-swapping powers to leave their own dying world for ours...
  • Mainstream Obscurity: Plenty of people probably have heard of Cthulhu, but have not read Lovecraft.
  • Magnificent Bastard:
    • A lot of portrayals of Nyarlathotep.
    • Thsathoggua.
  • Memetic Molester: Y'golonac, who is essentially the god of the bad touch.
  • Memetic Mutation:
    • CTHULHU FHTAGN!
    • IÄ! IÄ!
  • Older Than They Think:
    • Hastur originally came from Ambrose Bierce's Haita the Shepherd. Chambers used the name in The King in Yellow. In spite of Hastur's prominence in the works of later Mythos authors, H.P. Lovecraft only used it once as a casual name-drop in "The Whisperer in Darkness".
    • The term Fire Vampires were first used for Fthaggua's servitors. Latter, Call of Cthulhu used the term to describe Cthugha's Flame creatures, and became the depiction that most associate with.
  • Praising Shows You Don't Watch: Receives a lot of praise from people who know little about it besides that it's where Cthulhu comes from.
  • Seinfeld Is Unfunny: Similar to Slender Man in present day, some are considering the character of Cthulhu to be so overused and well-known that he's become a cliché of the Cosmic Horror Story genre. Fortunately, there's plenty of other monsters and villains in the Mythos for writers to use to avert this.
  • Squick: In Japan, Atlach-Nacha has been associated with this thanks to a certain video game.
    • One could consider the interbreeding between humans and the Deep Ones to be this since it's basically people having sex with giant fish.
  • Too Dumb to Live: The protagonist of "Fane of the Black Pharaoh" by Robert Bloch. Being led down by a cultist, the archeologist sees centuries of prophetic events, notably of visitors being lead down the Fane and soon killed. Guess what happens next?
  • Word of Dante: Several common aspects of the Cthulhu Mythos (such as the good/evil dichotomy and the Necronomicon as a powerful Brown Note) come from Lovecraft's friend, August Derleth, rather than Lovecraft himself.
