There's one type of movie that over the years has slowly turned into a different breed from itself, and that's the horror genre.  What used to be more psychological or general trickery of the mind to imply horror slowly turned into "whore"er movies where there happens to be more T'n'A then there is actual credible scares (such as most slasher flicks). Of all the monsters out there in the cryptozoological department, the vampire has been far hit the hardest by the modern-day glam machine, going from a tragic blood thirsty creature to a sparkling pretty-boy elven equivalent in the dead-man market, and so it's not surprising that when I want to watch a vampire flick I draw from an older stash.
