Imagine that you're reading one of those Twilight books as Edward is whispering chaste sweet nothings into Bella's ear, and it was oh-so-romantic-and-couldn't-you-just-die-OMG-OMG-OMG. Suddenly Edward's head flips back and his throat opens up like he just became a Pez dispenser. A six foot stinger/sucker thing flies out, and it zaps that silly girl right in a major artery and drains her dry in about twenty seconds while parasitic worms take over her corpse and turn her into a mindless bloodsucking meatbag. 
 And that is why Guillermo Del Toro will never direct one of the Twilight movies. Too bad because I'd pay good money to see that. 
 Del Toro, who directed several horror movies as well as the critically acclaimed but extremely gruesome Pan's Labyrinth, apparently was tired of the vampires being castrated by hordes of adoring teenage girls and set out to make them monsters again. And he does a pretty good job. 
 A Boeing 777 lands in New York but most of the passengers are dead. Before you can say 'Bela Lugosi', a CDC doctor is getting lessons from a Van Helsing wannabe named Setrakian on the best way to deal with the vamps, which are essentially a parasitic virus run amok with a Master bloodsucker as the main villain pulling the strings to launch a full scale vampire apocalypse. 
 The book had a fresh take on the vampire story and Del Toro and co-author Chuck Hogan do a good job of mixing some Old World vampire mysticism with 21st century science and tech. Especially creepy is the way that Manhattan is soon being quietly overrun during the initial outbreak. It's got a Stephen King 'Salem's Lot vibe in those descriptions. 
 However, Del Toro borrowed liberally from some of his movies, most noticeably Mimic and Blade II. The characters are B-movie thin, especially the hero who is also saddled with a bad sub-plot of a custody fight for his son. (His ex-wife and the social service worker can't understand why a potential viral outbreak might cause a CDC doctor to have to reschedule an appointment or two.) The opening set-up with a plane load of dead passengers has been used twice before that I know of in Nelson DeMille's The Lion's Game and Fringe in its pilot episode. 
 So the story seemed overly familiar in a lot of ways, and the writing isn't especially great, but it's got a lot of momentum and is loaded with enough gore and ultra-violence to make vampires nasty again. It's the first in a trilogy, and it was enough fun that I'll be checking out the next two.
