What do you mean, one group doesn't recognize the unreliable narrator thing, or is only slowly picking it up? Something like that?
I haven't watched any of Season 2 yet so I have been staying out of online discussions (actually did re-read TVL pretty recently but can I remember what happened in that particular book? No. But not worried about plot spoilers, just looking forward to reacting to the show's choices myself when I get around to watching) but I am curious about what people are saying in general
It's more of a case of
"How dare the writers make my favorite character an unreliable narrator, it's the other characters that are, HOW DARE."
And I've seen this sort of thing said about every one of the main four characters.
I've also seen book fans loudly flounce from the show fandom because the show is
"disrespectful to Anne Rice's works"
and
"They just wanted to make a version of True Blood with Anne Rice's name slapped on".
(Mostly because those fans are offended that vampires have sex.)
Which, if you've ever read any interviews with Anne Rice, it's pretty apparent she'd love the show.
