I think the anticlimax comes from the fact that Harry has basically no agency in the story at all. We get 4 lines of internal monologue, but really, this is Quirrelmort's story, not Harry's.
This isn't because he wins, so much as it is because his winning suddenly in this manner basically invalidates the entire rest of the story. While this might be an accurate rendition of events according to characterization, it ignores almost every subplot, begs the question of why this didn't happen at any other earlier event in the story, and doesn't really fit Quirrell's wistfulness over Harry's similarity yet difference from himself. Obviously that could all have been a lie, but even assuming everything done recently was to bring Harry to the point of matching Quirrell enough for the spell, this doesn't seem like the cutoff. The loss of Hermione's body shouldn't be the Despair Event Horizon for Harry - he was dedicated to getting to godlike power so he could just will it to happen.
Quirrell's knowledge of Ringmione also puts him in the reader's shoes really, it is something he could not have known, unless we assume a lot of things about the story were false.
I suppose a better term to describe the ending is "unsatisfying and plot ignoring".
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 97. The previous thread is at nearly 500 comments.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system.
