It's from a book that was written during the wave of rewriting the classics. (See Pride and Prejudice and Zombies and Sense and Sensibility and Sea Monsters.)
I read all of them through and thoroughly disliked them all. I'm not one to shy away from a book just because it's different and really do give a good faith try to get over any initial dislike and judge the book objectively. (I'm a voracious reader so I generally just enjoy reading.)
I love Jane Austen's novels and was absolutely prepared to love them with this kind of modern twist. The new writer simply hadn't understood the sheer wry wit and sarcasm she put into her writing sometimes and the additions were completely false, flat and out of place because of it.
With Abraham Lincoln: Vampire Hunter I thought it would maybe be a little bit better. No old and well loved book being jarred with a new writer's interjections. I was wrong. The whole book read like someone had mashed together the story with little editing or any attempt to refine it. While I thought it could actually be a funny and interesting idea for a book, it came across as a juvenile mash up of History Class and knock off Anne Rice novels. All in I have no intention of seeing the film because the book was so terrible.
