Oh, one thing I noticed was I know how the book ends. Harry gets together with Ginny and Ron gets together with Hermione. However, even now that this is the penultimate chapter, I can't see it. Emma and Rupert sold the possibility a lot better than Daniel and Bonnie (there is nothing between those two). But, I have to say, that if I was only going off the movies, I'd think that it was going to end with Harry and Hermione getting together. Their chemistry is perfect. You can't contrive that type of chemistry. Little things like Hermione resting her head on Harry's shoulder at the grave, the awkwardness, yet joy and comfort in the dance, the little kiss that she gave Harry when they met up at the Dursley's. Now that was all probably scripted, but the two of them completely sold it. I'm not a "shipper" but if it were just the movies, I would certainly believe their relationship above the ones that are going to actually happen.
The problem they have, and it's not really their fault as they cast them so young, is that despite the endings being Ron/Hermione, and Harry and Ginny, the girl playing Hermione and the guy playing Ron only have a bit of chemistry together, and the girl playing Ginny has zero chemistry with the guy playing Harry, and yet the actors playing Harry and Hermione have so much chemistry together it is unmistakeable.
Now what is their fault is that they compound this problem by a few more things. One, there is a lot of stuff between Harry and Hermione in the books that when it gets translated to film, coupled with the chemistry of the two actors, portrays them as the potential couple, much more than the brief moments between Ron and Hermione for example (especially due to the noticable difference in chemistry between those two couples). Two is the fact that in every film, the people writing them write little moments and interactions between Harry and Hermione that werent in the book to begin with, which just adds to the overal image. And thirdly is that so much publicity material for the films always involves Harry and Hermione together.
Now I like Harry and Hermione together, I could argue long and hard that this should have happened in the books (and have done in many threads on many forums), so I dont mind any of this and like it, but if you are not a H/H shipper I can appreciate you might not like it as much, especially if you feel the couple you did like is put on the back burner to allow Harry and Hermione more screen time.
