Topic: vampires oh my

So I'm procrastinating my real book in favor of a fiction Vampire story. And i was wondering what do you absolutaly hate to read about? what turns you off from a book and makes you want to gag the author?

Re: vampires oh my

I hate boring stuff that's been done before.  Like all the war fiction books, there's only so many stories before it's just boring.  I also hate conspiracy books only because it's so easy to say "hey, I thought about this, let's make a book"
