I filled out the poll, then read the comments and would change some of my answers.

I'm definitely in the "non-sparkly" crowd. (If it sparkles, it's something else - a fairy maybe, although probably not faerie, but I'm more flexible about that.)

Vampires are definitely parasitic.
Vampires are dangerous. Even the somehow contained or "friendly" ones are potentially dangerous. (By the end of the series, I didn't really think of Angel as a vampire.)
Vampire power is connected to sexuality in some way. (And their stories tell us a lot about cultural anxieties about sex, seduction, and loss of control.)

And then -
no sunlight (and it should take quite a bit of work to get around that)
strong in some way
immortal
invited in
no reflection
