However, the whole world feels so alive and real... and Rowling is such an incredible writer, she makes you not care.
On first pass, maybe. Rowling has created a heck of a world to be sure. But her writing skills within that world leave much to be desired.
NOTHING Harry does helps his own cause, for example. Harry is never allowed to be proactive. He gets held back time and time again until someone or something ELSE shows up to give him the means to succeed.
That's a primary flaw in Rowling's writing, really. Her protagonist is stuck in reactive mode. He is never allowed to better himself or his situation. Anything he acheives is DESPITE his circumstance, not because of it. That is done so she can hammer us over the head with her "choices not circumstances" theme.
And it's such poor logic. By rights, Dumbledoor (aka the Manipulative Old B***ard) was grooming the next Dark Lord with what he did to Harry.
Except of course that Harry didn't have the education needed to BE a Dark Lord. Which is another logic bomb in the books.
To Wit:
You know this kid is going to be the future salvation of the world as you know it.
What do you do? Ship him off to relatives who hate his guts based off some specious reasoning regarding "blood wards". Who treat him like a slave and abuse him (and NEVER get caught doing it). Never bother to check up on him. Allow critical parts of his education to be compromised by poor teaching (Snape, et al). And you don't step in to take up the slack?
No. None of it makes any logical sense. Too much "writer ex machina" thinking. To much happening "just because" and no logical consequences.
And don't get me started on the "romances"....Ginny the Cipher becomes Ginny, Love of Harry's Life? UGH! (though, given that her mother was a "potions princess" vis a vis her father...I have to wonder...like mother like daughter?)
Hermione loves a thoughtless, selfish, boorish prat who disses her on one hand and copies her homework on the other? BARF!
Rowling created a heck of a world, to be sure, and her writing STYLE is a genuine pleasure to read...the SUBSTANCE of her writing though does NOT bear close nor repeated examination.
