I couldn't agree more. I loved, really loved, all four of the books, (Although, Breaking Dawn had its moment of disappointment for me) but I was very disappointed by the movie. I think you hit the nail right on the head when you mentioned the lack of character development and the rushed sense. It's really too bad. I think if it would have been done better I could have lived with it not being the spitting image of the book. I'm skepticale about going to see New Moon now. I may wait for it to come out on DVD. I don't know yet.
On a side note, though...I just have to say that even in the book, as much as I enjoyed the book, when I got to the sparkely vampire; I couldn't help but think "cheese". Other than that, I thought the books were very well written. They were captivating and enjoyable but certainly not your everyday vampire saga.
