I prefer werewolves more than vampires, and I will tell you why.
Traditional western vampires are sentient parasitic organisms, who not only prey on the living for food, but also for pleasure. They ENJOY killing people. They are fully aware of their actions, and thus, worthy of contempt (in my opinion).
The traditional western werewolf is seen as a savage beast, a tortured, cursed soul, not aware of its actions, and while in human form, can be even REMORSEFUL about its bloodlust. to paraphrase Alexander Corvinus from the film "Underworld: Evolution", "At least they cannot control their savagery".
My other reason for liking werewolves more than vampires is due to reading my copy of "The Werewolf Book: The encyclopedia of shapeshifting beings" (a book I highly recommend at least reading) in which a man named Theiss is described. Theiss was an elderly man in the middle ages, who claimed that werewolves were not evil, but instead "Hounds of God", saviors of humanity, sent by God to purge the world of evil. He also claimed to be one such werewolf. For his beliefs he was put on trial and executed for heresy.
Despite Theiss's obvious insanity at claiming to BE a werewolf, I like his view of them, of werewolves as superheroes, as GOOD GUYS.
In native cultures:
(Correct me if I'm wrong) but shape shifters in native cultures were not feared, but revered and worshipped as being closer to nature than the average person. It was a good thing to be a werewolf, or any other shapeshifter and I like the native cultures version of shape shifters for that reason.
The Wolfman vs werewolves:
I like the Wolfman films, although I do not think a wolf man is the same as a werewolf. I think the Wolfman is more man than wolf, while werewolves are more wolf than man, at least from a physical standpoint.
I ALSO DO NOT LIKE THE TWILIGHT VERSION OF WEREWOLVES AND VAMPIRES, PRETTY MUCH THE ONLY THING I DO LIKE ABOUT THEM IS THAT THE WEREWOLVES AREN'T BAD GUYS.
I like werewolves to be tortured souls, remorseful of their bloodlust, or sympathetic characters, and I like when werewolves fight for good and not evil. Granted, that doesn't mean I don't enjoy werewolf horror films, however I do prefer my werewolves to be good guys.
I will add more as I think of it.
