From a survey on a forum I frequent: From Dr. Polidori's Lord Ruthven to Stephenie Meyer's Edward Cullen, the annals of vampire lore are filled with attractive, charming bloodsuckers. Which one would you most want to be bitten by?
You know, I'd be fine skipping the biting bit altogether and just sitting to a nice cup of tea and some chat about photography with Otto Von Chriek. But, if we must go the biting route, then I'd say Angel all the way (Spike's hot and all, but I much prefer James Marsters when he's snogging John Barrowman). Or, for a more old school tv vamp fix, Nick Knight (Is that not the worst character name ever?)
For a more literary bite, well, I'd sooner slit my own throat, or leap into a pit of sharpened sporks, than let Edward Cullen or any of Ms. Meyer's other sparkly kiddie craft project emo "vampires" anywhere near me. I'll take some wicked beautiful Lestat (only the book Lestat. Both film versions were horrid. Tom Cruise was a terrible Lestat, but Stuart Townsend was even worse). Failing that, I wouldn't refuse Louis (book or movie. I can deal with Brad Pitt).
Although really, I've been on more of a werewolf kick lately. So hell, let's throw some Oz (Seth Green on Buffy) into the mix as well.
