the idea that feyre is unreliable because she is 1st person pov while nesta is reliable because she is 3rd person (LIMITED) goes to show that acotar is the first series people have read in ages.
yes, first person narrators are limited to their own personal truths/thoughts/values/views of the world, that does not mean that they are purposefully lying or being deceptive. they are giving their perception of events.
i see people on tiktok (the land where intelligence goes to die) say that katniss is unreliable because she has low self-worth, doesn't pick up on peeta's crush, and thinks little of herself. but katniss is never trying to trick the audience and lead them to believe something that isn't true. that is not the purpose of katniss's narrative in thg. she is relaying her own truth/beliefs while assuming that this is the correct reality because she has her own preconceived notions that lead her to believe those things.
people do the same thing with feyre. "feyre thought rhys was evil in acotar but falls in love with him, she must have been lying. take that feysands! either feyre is an unreliable narrator because of rhys and she lies, or rhys is just evil!" as if feyre's dislike of rhys (and she always had nuanced opinions about him, people just love to forget about that) can't both be born from her perceptions and her perceived versions of events. she never is trying to lie to the audience (which is what unreliable narrators traditionally do), but she can be biased and led by her own emotions.
both feyre and katniss are also very open to changing their opinions and beliefs upon new information being revealed. that is not what an unreliable narrator typically does.
if feyre is led by her own biases, so is nesta. nesta's pov is 3rd person limited. although the narration is in 3rd person, we are limited solely to her thoughts, beliefs, feelings, and worldview throughout her pov. she is also not trying to lie to the audience, but it is her own perception of reality that causes her to view characters in a particular light. of course it's okay to question feyre's perception and critique everything about her pov (i've seen people go as far as to wonder how we can read her pov if she's illiterate...) but god forbid people point out something as obvious as this.
most 3rd person narratives are biased in a character's pov. if a character hates another character, events will be painted in an even worse light. if a character has self-esteem issues, they will think of themselves lowly, even if other characters' words/actions lead the reader to believe otherwise.
