These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: With The Slow Regard of Silent Things we have Auri: is she aware of the true nature of the world on a level beyond normal people, or is her behavior simply obsessive-compulsive?
Ass Pull: Kvothe and his team return from overcoming the Vintish bandits, flush with plunder and success...when Kvothe stumbles onto, is seduced by, and then whisked away by the Queen of the Fae, a fate that no man has previously survived with his sanity intact.
Fridge Brilliance: The Fae Queen violates her fundamental nature and lets Kvothe go without any real complaints, clearly humoring his incredibly lame excuse about needing more experience and generally behaving like a besotted wet blanket rather than a literal magical sexual predator... just after Kvothe has one of his in-setting unexplainable bouts of inspiration and pulls her capital-N Name out of nowhere. He wasn't just that awesome, he (or whatever third-party force is providing him with Names as needed by the plot) actually just mind-raped his way out of unavoidable doom.
Broken Base: The announcement that Pat would be releasing a novella centered on minor character Auri, The Slow Regard of Silent Things, had fans either excited to see a new perspective of the Kingkiller world, especially that of an enigmatic character, or disappointed that he wasn't devoting his attention to the much-anticipated third book. Upon release there was further split as some found the narrative uninteresting and irrelevant and criticized Pat for wasting their time, while others praised the unconventional story and its exploration of Auri's character.
Bast: [angrily waving a note Kvothe left him] What am I, some dockside whore?
Mary Sue: While not without relevant flaws, Kvothe is idealized enough to qualify for this this trope (impossibly brilliant, charming, tough...) His popularity, and the nature of his flaws suggest he might just qualify as a Deconstruction of either Mary Sue or The Ace.
The Edema Ruh are the greatest performers in the world. They treat each other like family, with no petty rivalries or distrust between groups. They're always kind and generous to fellow travelers. And they never commit crimes. The rose-colored view of the Edema Ruh might be due to Kvothe's personal biases as a fiercely proud Ruh himself.
The Adem, an entire society of warrior-philosophers. They're ruled by their elite mercenary schools, whose martial arts secrets are several orders of magnitude greater than any other society's. Even their lowliest, stupidest members look like superheroes compared to other people. Their leaders are selected purely on merit. They have absolutely no sexual inhibitions, yet also have absolutely no venereal disease. Their language is far more subtle and elegant than any other. They all have iron-clad composure. Their food is delicious. Their medicinal skill rivals the greatest academic institutions. They are technologically advanced. They live in great wealth and comfort, but without needless frills or vanity. They seem to lack crime, corruption and poverty. They do have a number of oddities, but they are all well defended: While their culture believes that women are basically better than men, they are a meritocracy, so their culture is basically evidence of this conclusion. They don't believe that men contribute to pregnancy, but even Kvothe cannot provide evidence to the contrary that they cannot refute with sound logic. They disapprove of music played in public, but only because they cherish it so much.
Plot Tumor: The interminable interlude of faerie sex. Someone counted the pages. 60.
Romantic Plot Tumor: Some readers think Kvothe's very slowly developing romance with Denna takes up too much time. In the second book, Kvothe acknowledges that he has to woo her extremely slowly, for fear of scaring her off.
Becomes Fridge Brilliance if you remember that Kvothe is a fifteen-year-old boy who's never had a crush before and this kind of behavior is pretty common in that scenario.
Strawman Has a Point: For all that Ambrose is exceedingly prejudiced against the Edema Ruh and abusing his influence to attack him, by the end of the first book Kvothe has in fact 1. Robbed him, and 2. Committed an act of extreme malfeasance.
The Woobie: Auri, due to her homelessness and implied Dark and Troubled Past. Kvothe after his parents' death manages to surpass Auri; the Tarbean chapters are downright painful to read. In ''The Wise Man's Fear," the two girls enslaved by the fake Edema Ruh.
