- Ros's status as a Canon Foreigner who takes screen time away from characters in the books makes her hated to a lot of people (being the main participant in most of the sexposition scenes doesn't help), but plenty of critics and viewers find her snarky, charismatic and sexy.
- Talisa Maegyr and Robb. Some viewers enjoy the expanded role that Robb's romantic relationship gets, while others dislike the new material for various reasons, including Talisa's Canon Foreigner status, viewing it all as a Romantic Plot Tumor, and seeing the changes as making Robb less sympathetic.
- Shae, largely due to her characterization being vastly different from in the book. While in the book she's a manipulative opportunist, in the show she's unreasonably jealous and vindictive. Fans are divided on whether the change works, especially once the Purple Wedding, trial, and her death are taken into account.
- Karl Tanner, leader of the mutineers of the Night's Watch. While Burn Gorman's performance was generally well received, the character is unique to the show, which upset some of the book readers. Some viewers also prematurely judged him to be a Small Name, Big Ego and were upset when he outclasses Jon Snow in a fight. Of course, most fans ignore that he fought dishonourably.
- Stannis Baratheon:
- Stannis was already fairly divisive, with fans giving him the nickname Stannis the Mannis from those who adore him and consider him the rightful king and others thinking he's just a boring character who also happens to be a religious fanatic.
- In Season 5, after Stannis sacrifices his daughter to R'hllor, Stannis fans divided on whether Stannis remains a sympathetic character or has done a FaceHeel Turn into a Hate Sink. A lot of book fans (including many who don't even particularly like Stannis) were more angry at the writers, considering that in the equivalent Cold Equation in the books Stannis refuses to burn anyone (not even captives or unbelievers) except as punishment for cannibalism and still seems confident of defeating the Boltons.
- There are several different debates around Sansa Stark. First, transferred over from the book fandom, considerable vitriol is directed at her in some quarters for (variously) being stupid, girly, or passive. Second, there are the people who like the book character and dislike the changes made to her by the show's writers (such as removing her involvement in her escape from King's Landing and being generally more sympathetic to Tyrion). Lastly, there are quite a few viewers who are extremely happy with show Sansa's portrayal, finding her to be complex, strong, and smart.
- Daenerys Targaryen:
- Some fans see her as a kind-hearted character who began the series as a victim of abuse and eventually becomes a Magnificent Bastard with the strongest claim to the throne, a really fancy wardrobe, and, of course, three badass dragons under her command. Others find her incompetent, overrated, and her lines to be full of Narm. Regarding the latter, there are different opinions on how much of this is either the fault of the writers or Emilia Clarke's acting.
- It should also be noted (albeit very briefly) that gender politics has some role in this: due to Dany ascending to Big Good as of Season 7 and apparently becoming The Hero; some people see her tale of conquest as highly inspiring and empowering for women and see her as a strong feminist role model, while others dislike how her importance and role have started to overshadow allegedly more competent and experienced male characters such as Tyrionnote and Stannis.
- There's a debate over whether her story is a classic rags-to-riches or a white savior story. The scene in "Myhsa" where she is called 'Mhysa' (mother) and lifted up by several hundred ambiguously brown freed slaves is particularly contentious, but overall the idea of a white foreigner suddenly arriving in the 'uncivilized' majority darker-skinned cities and then magically improving the lives of every slave rightfully inspires a little contempt. From there, the natural extension of an entitled white savior is to...go save another country that she's never been to, which happens to be exactly what she's hell-bent on doing.
- Her actions over the course of the series is also a point of contention. Some fans consider her to be a genuinely evil person much like her father or even Cersei, citing that she herself has taken slaves (Mirri Maz Durr, for one), is planning an invasion that will leave thousands of dead for entirely selfish reasons, and has executed hundreds of people in cruel and unusual ways such as crucifixion or being burned alive by a dragon (especially in the case of the Tarlys). However, others argue that she does not at all desire to murder thousands to obtain the throne, and the very few innocents (among many an Asshole Victim) she unknowingly killed caused her true remorse. Plus, she gave the Tarlys a choice to serve her (and Tyrion suggested they take the Black), but they refused and willingly chose death over betraying their Queen Cersei (whose own claim to the Iron Throne is morally dubious at best), adding to the fact that, in war, if an enemy soldier refuses to join you, they are still your enemy and should be taken care of. To add to this, she did not have to aid Jon Snow and let him mine Dragonglass or come to the rescue of Jon and his company from miles away while they were under attack by the Army of the Dead, nor did Tyron persuade her. It was her choice.
- Olly also gets a lot of hatred in Season 5 due to being whiny, anti-Wilding and for delivering the final kill on Jon Snow in the season finale. Other people believed that he didn't deserved that much hate and pointed out that Olly hated the Wildings because they killed his parents and destroyed his village in Season 4.
- In fact, his actions in the season finale could be justified due to believing that Jon let Tormund off the hook despite being one of the ringleaders who raided in his home.
- While many continue to applaud her badassery and Undying Loyalty, Brienne's killing of Stannis rubbed many fans the wrong way since they not only felt Stannis suffered from Designated Evil but were angered Brienne would abandon Sansa for personal vengeance and later gloat about it to Davos and hold a grudge against him even though she's Not So Different in serving people Because You Were Nice to Me.
- For many book fans in particular, this behaviour also bought into stark focus that the show's surly and vindictive Brienne is the antithesis of the kind, gentle, and idealistic character they love from the books who only kills to defend herself and others.
- Euron is either an entertaining and badass villain, an uninteresting and obnoxious one, or simply a pale shadow of his more intimidating Sorcerous Overlord book counterpart. Others say that he could have been a good villain, but he was introduced too late, making everything about him feel rushed and underwhelming, even though Pilou Asbaek's portrayal of him has been generally well-received, especially in Season 7. The biggest problem with fans and critics alike is that Euron is introduced right when the show has entered its notable nosedive in quality, to the point where his only role is to serve as a convenient plot device whenever needed.
- Varys from Season 6, as the entire Young Griff storyline was cut; with it went speculation on Varys' motives, making him simply interested in restoring the Targaryen dynasty. Some dislike that it simplifies his character from the books where he was more shifty, morally complex, and shown to have been working on his plans for "Young Griff" for almost twenty years. Others like the change because it makes Varys a moral and loyal man but no one trusts him because he's a eunich and a spymaster, which also works for the series' love of subverting tropes, while in the books Varys turns out to be just as ambitious a schemer as everyone else in Westeros and really is just as treacherous as everyone says, just layered in how he's treacherous. And then there's those who appreciate that the Young Griff subplot (itself controversial) was cut for the sake of Pragmatic Adaptation. Others were willing to accept a simplification, but not the Voodoo Shark the writers made of Varys' motives.note
