For some reason opaque to me, our civilization is in the midst of a Vampire Kick. From Goth fashions to best-sellers, the undead are unavoidable. So - purely as a cultural commentator, you understand - I've been sampling this trend. (Such scholarly plodding research.)
Lately I've been watching the short-lived TV show Moonlight. Enjoyed it. As much because of the cheesy dialogue, I think, as because the main vamp character is cute. I liked his best vampire buddy a lot (following him to Veronica Mars, a good and well-written teen-detective show that's surprisingly vamp-free.) Really, Moonlight's vamp-detective idea is just Angel-lite. I would strongly recommend first watching the it'll-be'classic Buffy the Vampire Slayer then its spin-off Angel. Angel the vampire has his followers, but for me, his show and Buffy are really the Spike Show. More vamp-y goodness (with more sex and gore) at True Blood. I haven't caught Vampire Diaries.
