I love American Vampire, it is definitely the BEST vampire comic out now (saying that, I can only think of two others: I, Vampire and 30 Days of Night). I've been on a bit of a Dracula binge as of late so I guessed the twist near the start. It was when Hobbes referred to that american characters as "Ren..." and I almost expected him to say "field". Still, fantastically written and drawn, American Vampire is just all around great.
I also loved the way they distinguished between characters speaking English and characters speaking French.
