Some people say the Civil War was fought over slavery. Others say it was a battle over states’ rights. The real reason: vampires. Thank goodness for “Abraham Lincoln: Vampire Hunter,” the other 2012 movie about Lincoln. Both films take liberties with the truth. This one, maybe a few more. It’s like a couple of stoners were watching the “Matrix” trilogy and said, “Dude, you know what would make this better? If Neo was Abraham Lincoln! And he was fighting vampire zombies!” It’s bloody good fun, actually. And it gives whole new meaning to the phrase, “The South Will Never Die.”
