I've been hearing about this fic for a long time, and I've been somewhat suspicious of it. I knew that Eliezer is a pretty good writer, but that his attempts to graft Bayes onto his characters are invariably rather inorganic. On top of that, OOC is irritating to me even when I expect it.
Nothing, however, prepared me for this. I just got done reading chapter 6. Up to this point, Harry's greatest sin was dumping a Less Wrong post onto poor Minerva every ten minutes. And she understood everything, including pop culture references (when in the books, most wizards don't comprehend rubber ducks).
Now, in this chapter, Harry thought he heard a strange note in the prof's voice, decided in a split second that she's trying to destroy his parents, and informed her of this suspicion in the form of a hissy fit. Then he started blackmailing her, and finished by implying that she's a nearsighted idiot, but it's alright, most people are. And he started calling her McGonnagal, then switched to Minerva, and is now planning on Minny for the future. I expected her to snap at some point and beat him to a pulp with the first heavy object that presents itself.
I read the reviews pertaining to that chapter. They all proclaimed it to be a masterpiece, the standard by which all other fiction should be measured. To me, it was what people call "epic fail". I cannot find any other way to describe my reaction. Calling it terrible just doesn't have that drop of vitriol that I think is necessary.
But this is Eliezer Yudkowsky. I KNOW he can write. I KNOW that he can detect and neutralize a Black Hole Sue. And yet...
Does he?
Voted down on grounds of not wanting to see similar content as a top-level post here. This has a tenuous connection with advancing human rationality even by the standards of the discussion section; it would meet a more receptive audience among Methods of Rationality's ff.net reviews, or in the MoR discussion threads here or on tvtropes if ff.net has some arcane policy against less-than-gushing feedback or if you're trying to shame Eliezer among his peers.
In any case, I'm starting to suspect that accusations of Mary Sueishness, among people predisposed to care, produce biased discussion about as reliably as bringing up any of the canonical mind-killers. Let's keep that rotting carcass out of this well, shall we?
