A personal issue of mine was the lack of romantic details in BD. We got descriptions when they kissed and cuddled during the other books but not when the big buildup finally happened. I was waiting for Bella and Edward to take their relationship to the next level, and SM just skipped over that part of the honeymoon. I felt the same about Bella’s first night as a vampire. Sure I can use my imagination, but just a few more details during two occasions...that's not too much to ask for in 700+ pages.
Don’t get me wrong, I know these are young adult books. I’m not saying there should have been graphic visuals or crude commentary, but a little sensual description wouldn’t hurt anybody! Certainly teenagers know it’s okay to have sex with your husband/wife, and they know how it works. At least SM did the right thing by waiting for Edward and Bella to get married.
Anyway, I mention this because I found the physical aspect romantic and necessary after so much time of caution and ignoring that desire. There was a much deeper connection there, sex just allowed Edward and Bella to explore a new outlet for the love and passion they felt for each other. After reading many of your responses, however, it's a good thing SM skimped out on details. There would have been a lot more backlash about the sex, seeing as people said there was too much of it and the young and/or conservative crowd felt uncomfortable.
Other things I wasn't fond of but came to terms with:
Charlie’s acceptance of ignorance (he was always overprotective and nosy)
Bella almost left Edward suicidal again (and she didn’t seem to care)
Renesmee overshadows the love story (essential to the Twilight saga)
Jacob’s imprinting on Bella’s child (though it grew on me) and a few dragging parts of his POV (though it did make me like him)
Bella loses nothing to become immortal (wasn’t that at the heart of Edward and Bella’s conflict?)
In exception to all that, I loved the book and the turns it took. I wasn't sure at first but, what can I say, I'm guilty of the Rob Effect in both aspects. If Bella had not had Renesmee, her and Edward would never have had a child together. Edward hated the thought of that; Bella didn't mind at first, but then she tapped into her motherly instincts. Anyway, now they have each other and a daughter and can live happily ever after in their "perfect piece of forever." yay!
As for the epic battle we all thought was coming - we were wrong to assume that. All of this disappointment is unnecessary. The cover of BD not only depicts Bella’s transformation, but it alludes to the “anticlimactic” ending. Like the art of playing chess, the battle revolved about mind tricks and manipulation, not a physical attack. It was a power game: which pieces could be used effectively? SM even used a page from The Merchant of Venice as a place for Alice’s clue - another story that centers on impending doom but does not end in bloodshed. (Would we have wanted that, anyway? Living without some of the Cullens? I don't think so!) Also, Carlisle repeatedly told everyone that there would not be a fight, only a chance to prove their innocence. They achieved their goal without violence and exposed the Volturi for what they really are. That’s a pretty big feat.I encourage everyone to listen to SM interviews or read the FAQ on her website to get a better understanding of Breaking Dawn.
