Though people seem split down the middle - it is either the dumbest thing they've heard or coolest- we here believe this is genius from a writing standpoint. In a good story the protagonist needs to have heaps of conflict thrust upon him. Who has had more conflict both professionally and personally in his life than Abe? As president he is trying to save the union with incompetent generals suffering defeat after defeat on the battlefield. At home he loses a son to sickness and his wife starts to go mad. And now he has to battle vampires without letting anybody know about it.
With the vampire overkill that has been going on lately A.L. Vampire Hunter seems to be a fresh and, I'm assuming comical, twist on a tired genre. The movie rights have already been purchased so we will have to wait to see if Abraham Lincoln Vampire Hunter will be inspired or simply a 21st Century Billy the Kid v Dracula. Which might not be a bad thing either.
