* {{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?"
* 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.
