I'm not a major fan of the series, so my opinions are not necessarily made as a starry eyed believer. It's been years now since I've read the book, but from what I do remember, the book and the movie were very much alike. This movie, like the book, plays like an extended third act that pulls back some from the action in order to not steal impact from the climactic final movie. I see comments like, Ron and Hermione forever and I don't necessarily agree with that. It seems to me, Rowling, resisting the clamor of her fans and their fan-fiction, to couple romantically Harry and Hermione, did so, by pairing Hermione with Ron. To me, this pairing cuts against the grain and is so obviously a mistake. Ron's a secondary character compared to Harry and Hermione. Even appearing on screen in soft focus, when he shares the screen with the two main protagonist. In the end, it was Rowling's book to write, as she saw fit and it still feels like a false note to me; an unrequited conclusion.
I post stuff like this on movie sites (and did post this) and I thought, I might as well, up it to my blog. Let me be clear, I post on and not for. There's a difference.
