Cronos: Early Guillermo del Toro interpretation of the vampire mythos. Basically about the fear of aging and death, and resisting the temptations of power.
Let the Right One In: Applies the Scandinavian genre of films about creepy dysfunctional children to the vampire mythos. Mostly a poignant and disturbing meditation on psychopathy, sociopathy, deviant sexuality, exploitation and enabling, but somewhat let down by an inadvertantly hilarious scene involving CGI cats.
Thirst: Gory Korean gangster-flick take on the vampire mythos. The general message is, never piss off either a) your daughter-in-law, or b) the village priest.
