Young vampires. Seriously, if you’re going to have an immortal character, make him old.
This post is inspired by the news the vampire in the US remake of Being Human (Pilot is free on iTunes atm, haven’t seen it yet but early buzz is good) was turned during the American Revolution. The BBC version was turning during WWI, makes him a century, what’s the point? And as much as I like True Blood, Bill was turning during the Civil War, makes him about 150. Edward Cullen is 105. @#%$!! HUMANS are older than that, granted they usually aren’t as active, but I think you get my point.
Now I’m not saying you have to be Methos (cookies if you get the ref), but I demand multiple centuries. Hell, Duncan MacLeod was young compared to most of the Immortals in Highlander and he was 400. Amanda was over 1,000. Lestat’s 350. Selene… (sorry, got distracted thinking of Beckinsale) was 600.
New rule: Immortals have to be old enough to have seen the Renaissance.
