It's bad writing. It's objectively terrible writing in fact. Purely on a volume standpoint, the average novel is 100K words. The Brothers K is HALF the length.

It's bad writing. It's objectively terrible writing in fact. Purely on a volume standpoint, the average novel is 100K words. The Brothers K is HALF the length. If we ignore that it's a rewriting of JKR's 7 novel series, which gives it a certain amount of coherency, Yudkowsky violates almost every writing guideline in a bad way. In fact, I could probably write an infinitely long coherent essay describing the ways HPMOR violates a reader's mind. It would be easy given almost 700K source material. But to point at some gaping holes, the plot has no pacing, and the entire story is a badly written self insert where the mc goes around and "fixes" JKR's plot-holes by writing themself into a corner. The solution to this, is, of course, to write another 20K words of expecto patronum, dispel the plothole with more rationalist bullshit. Your average fanfic is probably better written.
