Good question! You might want to ask carpenoctem-vampirology, I think she’s found a way to !!earn a living!! through her fascination with vampires, for which I will always be envious!

I find alot about them fascinating, mainly their psychology (human, but tranformed; they exist outside alot of the human struggle for self-preservation but are still subject to similar needs) and their physiology (how are they made? How are they destroyed? What’s the deal with crucifixes? What about coffins? How do their systems function on just blood as a nutrition source? What is up with those Dark Gifts? etc.).

However it’s not ALL vampires that are fascinating to me. I’m aware of the wide spectrum of vampire media out there, but the ones I find most fascinating (and that doesn’t mean they’re the BEST, just what I prefer) are:

• Ricean – This vampire species has so much baggage, excitement, chemistry, drama, and it tries to explore the how and why of vampires both as creatures and as people. Also they’re all pretty hawt.

• The Lost Boys – I just love the badassery of these vampires, very grunge and rockstar-ish and there’s the added bonus of kid!vampire hunters!
• 30 Days of Night – these ones are actually monstrous, not the kind you wrap in silk/lace/velvet and cuddle with by candlelight. I love the way the humans try to find a way to beat them, involving an enormous personal sacrifice. 
• Daybreakers – This concept is intriguing, a whole world of vampires, serving blood in ’50s style coffeeshops?! Also SAM NEIL as a vampire dad omg. 

• Let the Right One In – both the original and the remake… an exploration of what it’s like to become a vampire’s companion in the truest sense of the word. The vampire as a flawed creature who is still capable of love.
• Only Lovers Left Alive – Do you want to see SWINTON, HIDDLESTON, and WASIKOWSKA as vampires? AWWW YISSS. This was a modern-day idea of what it would be like to be this creature that suffers existential ennui, appreciates music and nature, nurtures kindness, is actually very fragile in their reliance upon humans for survival. And also blood popsicles.

• Dracula – the original, bc of reasons. How charming was Bela Lugosi?? omg he can bite me any night. 
• Dracula – the one with Gary Oldman, bc of reasons.
• Nosferatu – because I can’t have a vampire list and leave that classic masterpiece out. 
• Shadow of the Vampire – SO COOL like a behind-the-scenes of the filming of Nosferatu!

Probably missing something important here but you’ve had enough, haven’t you? lol.
