Assume HPMOR was written by a super-intelligence implementing the CEV of Eliezer Yudkowsky and assorted literary critics. What would it have written differently?
... is what I want to know, but that's hard to answer. So here's an easier question:
In what ways do you think Eliezer's characterisations/world-building/plot-fu are sub-optimal? <optional> How could they be made less sub-optimal? </optional>
(My own ideas are in the comments.)
To put it another way... Assume a group of intrepid fanfic writers in the late 2020s are planning to write a reboot. What parts of Eliezer's story do you think they should tweak?
And just to make sure we're all on the same page: Eliezer isn't going to go back and change anything he's written to bring it in line with anything suggested here. This is purely an "Ah, just consider the possibilities!" thread.
... which means that we can safely suggest drastic rewrites encompassing 30 chapters or something. Or change fundamental facts about the world.
(Exercise due restraint on this one. Getting rid of the Ministry/the Noble Houses/blood purism would probably turn the story into something completely different; this isn't what we're trying to do here.)
With that, let the nit-picking begin!!
My meta-comment is that you should have posted this in whatever the current HPMoR discussion thread is. It's an established community norm that talk of the fanfic should be kept there. Downvoted for that reason.
My regular comment:
I would have had Eliezer spend way less time on the "Hermione fights an endless supply of bullies" subplot. I wouldn't be averse to just removing it entirely.
I would also have all these damn hints and suggestions and leads and such be made explicit or way less subtle. I'm stupid and busy; I'm not going to get them on the first read, and I'm not going to read twice.
I LIKE subtlety. It flatters my ego if I see it, and if I don't, I don't know that I'm missing it. I hate how modern cop dramas feel the need to explain the significance of every clue to the viewer as soon as a character understands it. If you miss it, you'll eventually figure it out when the plot comes around to it.
