* {{Anvilicious}}: Religious extremism and intolerance are bad, inclusive spirituality and freedom of religion are good.
* {{Les Yay}}: Morgaine with half the women she encounters
** Morgaine and Raven (it's implied that these two actually do have some sort of physical relationship)
** Morgaine and Gwenhwyfar (doubles as {{Foe Yay}})
** Morgaine and one of {{The Fair Folk}}.
* JerkSue: Morgaine comes off as this, mostly due to ProtagonistCenteredMorality; she does some pretty JerkAss-y things [[spoiler: such as cheating on her husband with his son]], but the text never really calls her out on it. Possibly [[JustifiedTrope justified]] by the fact that Bradley wrote the book largely to make Morgan Le Fay sympathetic; she just did it [[{{Anvilicious}} in a rather unsubtle fashion]].
* {{Narm}}: At one point Morgaine laments the fact that all the men she's fallen in love with [[IncestIsRelative have been closely related to her]]. It's meant to be sad, but comes off less as "Fate has treated me cruelly" and more as "Why can't I stop falling in love with my relatives?"
* OvershadowedByControversy: In 2014, Bradley's daughter went public with the fact that she had been molested by both her parents during her childhood, and she was far from the only one, suddenly putting Bradley in the same company as Roman Polanski and Woody Allen regarding the debate over how much of an artist's own life should impact the judgement of their work.
** HarsherInHindsight: This revelation makes the dynamic between Viviane and Morgaine (especially regarding the Beltane ritual) ''so much creepier''.
* SeinfeldIsUnfunny: In regards to feminist treatment of the Arthurian legend. Nowadays, there are a fair amount of retellings from a female perspective (such as ''{{Gwenhwyfar}}'' and ''[[https://www.kirkusreviews.com/book-reviews/nancy-springer/i-am-morgan-le-fay/ I am Morgan Le Fay]]''), many of which take a less [[{{Anvilicious}} heavy-handed]] approach than ''The Mists of Avalon''. It's easy to forget how groundbreaking [=TMoA=] was, in spite of its flaws.
* {{Squick}}: In the book, while Morgaine is preparing to greet the Horned King, she Sees that the little girl who scattered blood on the fields is being ''raped'' by a sinewy old hunter. And Morgaine is apparently cool with this? Oh, and about a page later she realizes she's had sex with [[spoiler: ''her own brother.'']]
** Lampshaded when Nimue needs to pass water and is afraid to do it in public. Morgaine is puzzled as to why would anyone want to spy on someone passing water.
* {{Well Intentioned Extremist}}: Viviane wants to save Avalon, but the methods she uses are highly unorthodox.
