I genuinely did overall like the concept of Magnus just being an obsessive fan. Like, in the moment, it really made sense and worked for me.
Again though... There's a lot to sort of unpack, or at least acknowledge, in terms of what they changed.
In the book, Magnus is going through a veritable hoard of tall, able-bodied, blond-haired, blue-eyed white men, because he's trying to find the "strongest" person he can to leave his legacy and fortune to before he ends himself.
The racism implied in this is a feature, not a bug, because The Vampire Lestat is Anne Rice's intentional, racist, pro-white-supremacy manifesto. Once Lestat is turned, he begins to embody the power, privilege, "burden" as a foremost protector of the West, particularly "modern" Western philosophies and "morality."
Lestat finds Magnus gross and scary and disgusting when he's initially kidnapped. But the minute he's turned into a vampire his perception changes entirely and he falls in love with him (this is how everyone falls in love in TVC, instantaneously and usually without explanation). He is deeply saddened when Magnus throws himself into the fire, leaving Lestat without direction for his new role as the paragon of white perfection, a gap that will later be filled by Marius.
Reading these books as an adult, it would always be a strange idea to adapt them without any acknowledgement of Anne Rice's open, blatant, and foregrounded white supremacy. But you COULD do it. People have been doing it for years in fandom, either because they didn't like it, or more often because they didn't really understand how to read it for what it was. (Or in the worst cases, because they DID understand it and DID like it.)
I wouldn't think that not addressing the racism at all is the best move, but like I said. It's physically doable.
The problem now, though, isn't that they chose not to engage with it at all ever. It's that they very much DID choose to engage with it and Lestat's racism overtly in s1.
Having Lestat's turning have NO element of white supremacist framing to it now... just... doesn't bode well for the weird gap of understanding - the functional amnesia it seems we're all being expected to have - around the concept of race and racism in the show.
Especially as it pertains to 1. Lestat as a character, and 2. Lestat and Louis/the Unholy Family.
