Number 3: Castlevania Series

I know this isnt a movie, but just humor me, this is a great game and it has 2 great elements Legendary Vampire Hunters and Legendary Vampire.
The story follows the accounts of the Belmont clan that swore to hunt the creatures of the night from the first known Belmont Vampire hunter Leon. The oath has been maintained as ever century Dracula rises from torpor to engulf the world in darkness, and every time he does so, there is a Belmont ready to take on the task to Slay vampires and demons alike.
The Belmont´s are shunned for their supernatural powers and abilities to channel their faith into holy relics and sacred weapons, particularly the Holy cross, Holy water and the legendary chain whip The vampire killer.

Gabriel Belmont

The castle it all takes place is a living entity that changes form with each reincarnation of Lord Dracula,  in this universe Dracula is the living (or rather undead) representation of evil in the world and has such power that he commands legions of undead and even the Angel of death. But Dracula is vanquished by the will and power of the Belmont clan and in many cases claiming the life of the Belmont that destroyed him.

What is a man? A miserable little pile of secrets

Dracula can be resurrected by mortals via a dark ritual in sacrificing a virgin at the altar where he was defeated. Amongst the vampire hunters that rise to slay him his own son a Damphir called Alucard (Dracula backwards) confronted him on two occasions, since Dracula despises humanity for killing her beloved Elizabetha when he was mortal and in his immortal life Lisa was burned at the stake for curing the sick, condemning her as a witch.

If you dont play the games at least read a comic or manga of this series, it is one of if not the best vampire series out there.
