I'm reading MOR with considerable interest and enjoyment-- and recommending it-- but.....

There's a big emotional difference between HP and MOR. In the original, Harry has no friends or allies at the Dursley's. In MOR, his family life isn't great and he doesn't seem to have any friends or anyone he's expecting to miss, but he isn't under constant attack.

Part of the emotional hook in HP is that Harry is almost immediately in a circle of friends and acquires a family in the Weasleys.

In MOR, his best emotional connection is to McGonagle, but it's complicated by his intellectual dominance. None of his close friends from HP are worth being close to (or did I miss someone?). His nearest approach to a friend his own age is Draco, and that's very much complicated by Draco having been raised to be a sociopath, and by Harry's need to manage Draco.

Part of the charm of HP was that Hermione's memory, intelligence, and conscientiousness are presented as more valuable than annoying, though the annoyance for the other characters is still there. This is a rationalist feature of HP which seems to be lost in MOR-- Hermione is interested in getting things right for the sake of status.

Her delight at being in a Romance completely eclipsing the question of whether she likes Harry is depressing, but within the human range, I think.

QuirrelMort setting up the Harry's structured humiliation no doubt has plot reasons, but I can also model it as organizational hysteresis-- after Harry made such a strong power grab in re Snape, it's plausible that great efforts will be made to remind him that he's just a student.

I have a notion that it wasn't just his mother's sacrifice that saved Harry, it was also something he did, and his reflexive rage and need to win is hooked to what he did to survive when he was a baby.

is the training that Draco is getting from Lucius based in anything from the novels? The Dracos never impressed me. They just seemed to be rich and mean, and the Pure Blood campaign is weirdly abstract and idealistic compared to their temperaments. (Is there a reverse halo effect where all bad qualities accrete something which is considered to be bad? The Dracos are bullies, so of course it's reasonable to turn them into Nazis.) To my mind Slughorn is part of the real range of Slytherin possibilities.
