I gave Grahame-Smith a try even after not being able to make it through his Pride and Prejudice and Zombies (for the record, I cheated, I tried to do the graphic novel). I thought that I hated P&P&Z so much because it besmirched my beloved Austen, but reading Abraham Lincoln made me realize that I don't like how contrived Grahame-Smith's stories feels...I know, I know. You KNOW that going into it. You know that Abraham Lincoln wasn't REALLY a vampire hunter and that the Bennet sisters (P&P&Z) weren't really trained in zombie combat...but be clever for Heaven's sake! Don't make every bad guy a vampire or in league with vampires! I literally rolled my eyes and shouted, "AWWW! C'MON!" when Edgar Allen Poe made an appearance in ALVH.
Maybe I love history too much to find any entertainment in this. Would I suggest it? No. I think I'm leaving this for that whole Twilight crowd, those people who are really into vampire stuff right now. Don't worry, we all go through that phase...really...I won't even say how many Anne Rice books I read as a teenager.
