Is it too much to ask for a little blood-sucking?

I recently caught the latest installment of the Twilight Saga, "Eclipse." Yes, I have seen all three movies, and no, I haven't read the books. I'll admit I'm a fan of the vampire movie/television genre, but lately I've been a bit disappointed. Whatever happened to the blood-sucking, soul-less demons we all loved to hate? Vampires have gone soft. If you need proof, look no further than Twilight's hero, Edward Cullen. Instead of lusting after the blood of innocent villagers, Edward only has eyes for Bella. But wait, he doesn't even really lust after her -- he wants to wait until they're married to have relations. All arguments about the legality and practicality of a vampire-human marriage aside, come on man, don't you just kind of want to eat her? It's no wonder all the teen girls are flocking to Team Jacob, I guess werewolves are the only real men left out there these days (except of course for REAL men, but dating humans doesn't seem to be an option for young Bella.) The friendly vampire theme can be found outside of the Twilight Saga as well. Another film that's out on video now is "Daybreakers," starring Ethan Hawke. In this sci-fi thriller a virus has turned the majority of the world's population into vampires. The remaining humans are hunted and farmed for their blood, but as the human race dwindles, an alternative food source is needed. Hawke plays a vampire who is sympathetic to the human plight, survives off only animal blood, and dedicates his time to creating a synthetic blood substitute, eventually teaming up with the humans to find a peaceful solution to the problem. "Daybreakers" is by far a much more interesting and unique twist on the old vampire tale, and I actually really enjoyed the movie, but again with the non-killing. One of my favorite shows back in high school was "Buffy the Vampire Slayer," in which the character Angel was a vampire whose soul had been restored, thus making him one of the "good guys." At the time this was fresh -- now this idea seems tired. My issue is that when every movie or tv show keeps trying to come up with a new twist or a different variation on the theme, variation itself becomes cliche and redundant. Meaning the "vampire with a heart of gold" story is no longer the exception, it has become the rule. So basically, if all the excitement Edward Cullen can muster is that he's a well-mannered vampire who enjoys long walks on the beach and big hair, sounds like he's a pretty dull guy. We've been there, done that. I'm ready for some good old-fashioned neck chomping.
