I enjoy the movies. I do feel the vampires could be way more... badass, though. 'Tough' even without killing innocent humans. Also, you rarely see their fangs. The glittery thing, I actually found quite clever when I read it in the books. It was a new change to vampires that I felt was creative. If you read the books, it isn't "glitter" it's more like a glow or shine to their skin, where a human could tell there was something eerie about them, but not quite put their finger on it, if they were to see it. I have yet to see the final movie, but I know what happens. I'm quite concerned with how they'll project Bella's talent. In the book, it almost seems cheesy that she is all powerful with it (once she hones it in) but what else could be her talent to end the story happily?
Oh god, in Part I where Jacob is 'becoming Werewolf pack leader' is so fucking bad, I laughed out loud. It is WAY better done in the books.
