Daybreakers

I'd got the impression that this one might be an unusually stylish, intelligent vampire flick, and while that's probably a fair call, it's also undeniable that the film's genre heart is very close to the surface. It goes like this: most of the world's population has been turned into vampires by a mysterious outbreak, but apart from a newfound thirst for blood (preferably human), things go on much as before...until the human blood supply begins to run low, it becomes apparent that a vampire deprived of blood undergoes a degeneration to a rather more atavistic and terrifying state, and a small group of surviving humans stumbles upon a cure for the vampirism. Neat concept, but it doesn't do all that much with it, being content instead to make the predictable moves en route to its bloody climax, with the result that it feels like an opportunity missed.
