One of the more interesting recent films about the paranormal was Stakeland. In that universe, vampirism becomes widespread across the USA. But though it does, the vampires are not unable to be controlled. They're even affected by the weather. By doing this, the writer could have them as problems to solve, while other humans used them as a weapon against other groups of humans. That was far more interesting and creative. I fully expected for the winter to affect the walkers. Nope.
