Vampires have always served as a wildly popular source of entertainment. Fiction about them dates back to the early 19th century and first truly immortalized (so to speak) by Bram Stoker in 1897.

They've been fascinating us for generations – who knows, maybe even your grandmom fantasized about Count Orlok (sincere apologies for the imagery) – and have been a steady presence in film for a century.

But is our lust for blood(suckers) now hitting a fever pitch? They're everywhere we turn – from megaplexes (we're in between 'Twilight' installments, with films like 'Daybreakers,' 'Buffy the Vampire Slayer' and 'Dark Shadows' to come) to art houses ('Let the Right One,' this week's release 'Thirst') and cable (this fall's 'Vampire Diaries') to premium cable ('True Blood').
