I became a Buffy believer just this year, and promptly devoured all seven seasons, along with the continuing "season Eight" comic books. I'm settling into Angel now.
My fave vampire movies have mostly been listed elsewhere on this thread already. In general, I tend to favor scary, non-sexy vampires over the heartthrob variety, because I want to be scared, not lulled into a woozy romantic swoon. (Buffy has loads of both.)
This thread is just begging for me to link to
my own Dracula play, which is too long and difficult to stage, and I'm currently slicing down into two acts for a tenth anniversary revised edition. (I'm going to miss the official anniversary by a bit.) Anyhow, it's got vampires, it's got romance, but not at the same time. Please forgive my shameless plug.
