I really ended up liking the book and I was skeptical! I found it slow at first, easy to read but nothing really exciting but when the whole James hunting Bella thing happened it got interesting.
I really enjoyed Bella and Edward's banter between each other as well.
I am not sure if I know what you mean by expecting the reactions of the characters? I think early on it was pretty clear that Bella was not afraid of Edward or even of dying it seems, even though she maybe should have been so I wasnt surprised by her reactions. I think the author did a good job of setting up the characters so that the reactions werent really out of the ordinary for them. Maybe the only one that did surprise me was Alice because for some reason, until the hunters I had this feeling she was going to be a thorn in their side as well, but turned out not to be the case
