I know what you mean! I've seen Twilight "inspired" covers all over the place. I'm pretty sure Wuthering Heights' and Pride & Prejudice's covers have been given a "make-over"... there might be others, but their names escape me at the moment. One/many of them have "Edward & Bella's favourite book" stamp on them. That is just wrong, and totally taking advantage of the publicity. It makes me cringe. I wouldn't buy a book with that stamp on it. :/

And yeah, the Blood and Chocolate movie was really quite... bad. I distinctly remember being unimpressed. I've been meaning to read the book, though, as I've heard good things about it.
