So Eliezer said in his March 1st HPMOR progress report:
I recommend the recursive fanfic “Friendship is Optimal: Caelum est Conterrens” (Heaven Is Terrifying). This is the first and only effective horror novel I have ever read, since unlike Lovecraft, it contains things I actually find scary.
So I read that and it was certainly very much worth reading - thanks for the recommendation! Obviously, the following contains spoilers.
I'm confused about how the story is supposed to be "terrifying". I rarely find any fiction scary, but I suspect that this is about something else: I didn't think Failed Utopia #4-2 was "failed" either and in Three Worlds Collide, I thought the choice of the "Normal" ending made a lot more sense than choosing the "True" ending. The Optimalverse seems to me a fantastically fortunate universe, pretty much the best universe mammals could ever hope to end up in, and I honestly don't see how it is a horror novel, at all.
So, apparently there's something I'm not getting. Something that makes an individual's hard-to-define "free choice" more valuable than her much-easier-to-define happiness. Something like a paranoid schizophrenic's right not to be treated,
So I'd like the dumb version please. What's terrifying about the Optimalverse?
The biggest horror aspect for me (also from the original) was that (rot13) nal aba-uhzna vagryyvtrapr unf ab punapr. Aba-uhzna vagryyvtrag yvsr trgf znqr vagb pbzchgebavhz, gb srrq gur rire tebjvat cbal fcurer. Vg vf gur gbgny trabpvqr bs rirel aba-uhzna enpr.
