Perfect Evolution (and the Buried Soul)

An interesting point, but there are much shallower traits that are the driving cash behind these films - marketing lust, fetish and violence to a young men's audience. They are all cheap knockoffs of the Matrix formula, as happens in Hollywood trends.

The seduction of evil (the vampire bit) is part of it. Evil is an inticements to something which hurts/kills another (vampirism) But it's not the critical factor - a Hollywood producer is not gonna get backing for a movie about homely-looking vampire girls in an emotional, dramatic story without violence. The audiences seeing these films could care less wether the black/red leather-clad woman is supposed to be a vampire, an alien, or robot. Lust and violence (the femme fatale) is the main driving force - the vamp stuff is a just a supporting role.

Another trait they all share is a militant feminism/dominatrix fetish. The scantily clad female beats the crap out of hundreds of male actors, who trade in their gonads for "fame" and fortune to be wussy punching bags in these films. This is a peversion of reality, and a unfortunately, an established sexual fetish in our culture. A good psychologist could explain why some are drawn to that crap. But it's definitely a trend that these type of films are trying to capitalize on, and its a bigger theme than wether than characters are vampires or not.

Of course the most common trait of all is, these films have been bombs at the box office. BloodRayne was practically shipped to Blockbuster the day after it opened and UV is still scraping to get above its production cost. With films needing to make 3 times their cost to break even, producers have lost money here. There is a bizzare Hollywood trend at work where producers are willing to lose money to make these kinda films that moviegoers consistently reject.

Its not like they were trying for some dramatic creative breakthough that a studio was willing to roll the dice for. These are tired formula pictures, based on marketing lust and feminized violence, with a vampire face.
