I have not read the books, nor have I seen the movie, so I really cannot form valid opinions. All I know is that, from what I've heard of it, it never seemed like anything that would be my cup of tea. I've never been into vampires much - and if I feel in a vampy mood, I have three manga volumes of "Hellsing" on my bookshelf. - And that features blood, gore, fangs and all that - while many anime/manga fans think Alucard is "hot," he is most definitely a monster and poor Seras is just someone he picked up on a whim, as I recall, and it's an action/horror series, not a romance. Then there's the "Crossfire" side stories in the back of the books about the assassin-nuns and that's just fun.
Shadsie prefers good old-fashioned blood to emo?
Anyway, online friends who tell me they've read these books in part or in whole tell me that my writing is a lot better... which makes me wonder why I'm not a published author yet when they're so successful. But, I guess the publication world and the public prefers vampires to morally-conflicted gryphons and peaceful, young, traveling scientists. And I don't think I can write a good, sappy romance to save my life (it's not even a heavy presence in my fan-fictions and they're a lot easier to write than original junk).
I don't know. No real opinion on the Twilight books/movies - all I know is that if my work ever became that popular, I'd be very flattered, but if I had swarms of fangirls and fanboys obessing over it to the point of treating it like holy writ and me like a goddess, I'd hold a press-conference to tell them to "Go get lives. Please. I'm not that great, go read some classics."
