The horror of having to spend centuries on the run, hidden from both society and your own kind who want you dead, living in a continual series of hovels and slums, void of warmth, friendship, tenderness and love... None of these things are as bad as an evening in Hastings. Imagine Croydon by the sea, but somehow angrier.
Anyway, the film's all, like, boring and shit and I think in this one people become vampires by watching birds fly up a pipe or something. Having said that, I'd watch Gemma Arterton in pretty much anything. Y'know, for wanking purposes.
