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.
YMMV: Discworld
Alternate Character Interpretation: There is quite a substantial group of fans who hold the view that Carrot is evil and/or The Chessmaster. It helps that he is almost never the POV character - we get to hear what Vimes or Angua think about him but hardly ever see Carrot's actual thoughts.
He has also set up Vetinari Job Security several times: the most obvious is in in The Fifth Elephant when he leaves to pursue Angua and Fred Colon is left in charge, the watch falls apart. Not surprising given that it's Fred Colon, but Vetinari lampshades that as everyone knows Vimes and Carrot will be back soon, no criminals take advantage of the Watch’s self destruction for fear of their wrath. The book ends with Carrot very politely bullying the collapsed watch back into shape by reminding them they swore an oath to the king to do their duty.
When Vetinari has trouble reading your motives, says things like "You drive a hard bargain, Captain." and you reply "I wasn’t aware I was driving a bargain at all, sir." and live you have to be The Chessmaster, albeit probably a benevolent one.
Archive Panic: There are currently 39 books in the series, not counting the various canon supplementals.
The Auditors of Reality. Blue and Orange Morality be damned - NOTHING that hates everything that lives - no matter how small or harmless - purely because it's messier than absolute sterility can be anything other than this.
Despite Vimes' almost suicidal urge to be normal in a World Full Of Crazy, he often does things that fall under Refuge in Audacity, such as arresting the military leaders of both Ankh-Morpork and Klatch under charges of Behaviour Likely To Cause A Breach Of The Peace in Jingo.
AE Pessimal. Attacking a troll, of all things, with your teeth is pretty insane, especially when you remember trolls are living rocks.
Granny Weatherwax started out as a supporting character in Equal Rites, but basically took over the book from the real protagonist by sheer force of awesome and ended up being the focus of the rest of the books set in Lancre.
Same with Vimes and the Unseen University taking over the Watch series and the Rincewind series.
Iron Woobie: Despite being the perpetual Buttmonkey, Verence always tries to do his job: be a fool and advisor to his king; an enlightened king to his people; and a husband to Magrat.
Magrat herself has a lot of this, as does Agnes Nitt.
Lady Margolotta, who is also a Bastard Understudy. In The Fifth Elephant Vimes initially assumes she taught the young Vetinari, but turns out it was the other way around.
Moist, Magnificently self-Lampshaded:
"I wonder... am I really a bastard or am I just really good at thinking like one?"
Marty Stu: Carrot is something of a parody of this, with lampshade hanging by other characters who have trouble believing someone so perfect can be real. More specifically, he's royalty, and has all the tropes of the Royal Hero coming from humble beginnings behind him... except he just wants to be a watchman.
In Maskerade, Granny Weatherwax lists, in suspiciously specific detail, all the things she would do to someone physically, if she were a bad witch. But as she's not she just laughed an in no way evil laugh, and went to deal with Salzella via headology.
