I could be wrong, but it seems as if some have misinterpreted the point of the list. It's not the 17 greatest vampires, it's the 17 hottest vampires.
And while the criteria for each one of those lists certainly wouldn't be mutually exclusive, it is different. And probably the biggest indication of that is the fact that Jonathan Rhys Meyers' Dracula is a part of the list even though we've just begun to see him as Drac, so his greatness in the annals of vampiredom may be yet to be determined over the course of the 10 ep series, but all that was really needed to make the hottest list is that JRM has been judged to look hot while he portrayed Drac in the first ep of the series. And why do I suspect that there are more than a few members here who think JRM most definitely looked hot while he did it?
