Vampires have gotten way too far from their folkloric roots.
The vampire legends of the 18th century stressed that vampires were tempters. Vampires persuaded people to do things contrary to common sense, piety, etc. Frequently vampires were undead family members who relied on familial loyalty to get the victims to open the door.
Vampires like Alucard from Hellsing might be wonderful characters, but they don’t tempt.
Sometimes when you get too far from the roots of the archetype, the original archetype is lost.
Somewhat like a fluffy duck with a switchblade.
