Lemme 'Slytherin' the discussion.
I've been a Potter fan since I've picked up the first book when It was published (and of course translated), I was...probably seven or eight years old.
We need to separate books from movies, and we need to do that pronto. Movies were good, actors were good, but movies will never ever ever ever replace the books.
In the books, and I feel I can say it safely because in this fandom I am a non-shipper (actually I am, but I only ship Jily), it has always been quite clear to me that the canon ships we got were the ones that mama Row always intended to, no deviation or anything, and I appreciate it very very much.
Apart from the fact that I adore Book Ron and mostly because his faults, insecurities and overall silliness, I can admit that Book Ron is almost certainly not Movie Ron, he's much dorkier and funnier in the books, just as much as Book Hermione is NOT (and I want to stress not) like Movie Hermione.
Nevertheless Harry and Hermione share one of the most beautiful bonds of all the series, maybe they are soul mates, but I never had the feeling that they should end up together, they work best as 'soul-bound-friends', their bond is perfect as it is, and maybe putting them in a relationship would have diminished it, at least imo.
Every time I see someone comparing Kishi to JK I die a little inside, she taught me to dream, to be inspired and I grew up with her books. She never betrayed her work and she created one of the most fantastic stories ever told (yes, I am that big of a fan).
JK Rowling emphasized bonds, and not only romantic ones. She wrote of loyalty, of friendship, of courage and of love and her books will be the ones I'll read to my children when they'll go to bed at night.
She gave morals, beauty and magic to all children of the world, children that grew up with her books, waiting with baited breath for the next one to be published (God, I mss those times!!) and comparing her with Masashi Kishimoto (the man who ruined his whole work like that, and still has the gall to be all smiley) is blasphemous....

But they were all of them deceived, for another canon was made. In the land of Japan, in the fires of Studio Pierrot, the dark Lord Kishimoto forged in secret a master canon, to control all others, and into this canon, he poured his cruelty, his malice, and his will to dominate all life. One canon to rule them all.
