One of the biggest question marks of the summer movie season has been "Abraham Lincoln: Vampire Hunter," Timur Bekmambetov's $70 million R-rated historical mash-up that sees the sixteenth President of the United States fighting undead creatures and the evils of slavery, all at the same time (in 3D, no less). Based on the novel by Seth Grahame-Smith, who also wrote the screenplay (with uncredited help from Simon Kinberg), and produced by top ghoul Tim Burton, the trailers and television spots didn't completely convey whether or not it was supposed to be funny or scary, serious or silly. It turns out that (brilliantly) -- it's both. Somehow the movie manages to be fun and tongue-in-cheek without ever seeming disrespectful. It's a winning combination of history and horror where Honest Abe is able to kick serious ass.
