To me, a guy, the book was OK. I was way into the concept of the book. It dealt a little too much with Bella's feelings, the way her heart beats, the way her pulse races...
I can see where the book would be more interesting to women. If you can get past that, then the book is a fairly entertaining read. I did actually read the entire series. I guess mostly because my wife did and the books were there. I can say this, the books get better and better. They move further from being centered solely on Bella's emotions and more into an overall external plot. Just my opinion.
I found the film to be less interesting than the book.
