I didn't hate it until a friend read it and made me read it, saying Bella is the person she's always wished to be.
I read it, and Bella is a person who believes she's worthless, and seems to make it a self fulfilling prophecy. She thinks there is something noble in loving and sticking by a man who is emotionally abusive with obsessive, stalkerish tendencies. Not to mention that he seems to always be on the verge of adding physical abuse to his list of "merits." The best thing these books have done is given me an insight into some of my friend's most self destructive tendencies. All her boyfriends have been like Edward, and the result is always catastrophic and leaves her even more convinced of her unworthiness in life.
I'm surprised this book is so popular with young girls. I would think its target audience would be men who believe in the old timey beliefs of female submissiveness and obedience. Ugh.
ETA: As for whether the books themselves are well written, Stephen King summed it up nicely. I'm sure this quote may have been posted before, but something that is true can never be posted too many times.
Both Rowling and Meyer, theyre speaking directly to young people. ... The real difference is that Jo Rowling is a terrific writer and Stephenie Meyer cant write worth a darn.
