We learn that Angie and Rachel are actually sisters in the vampire underground in NYC that Lindenmuth details. We are introduced to new vampires as well, and learn that they can live for centuries. We also get the opportunity to watch Angie entice yet another human into the vampire fold by way of Trisha, a young woman who despite her somewhat innocent appearance, makes an excellent apprentice. Addicted to Murder 2 is absolutely excellent. It raises the series from good to an outstanding contribution to the genre.
Many directors take a stab at the vampire genre, but few revisit the theme in future films.
Recently I had the opportunity to ask Kevin why he has returned to the vampire time and again in his films. They are like exaggerated versions of people's characteristics and they're not bound by morals. They are free to do what they want, which I think is also appealing. People are standing up and taking notice of this director's talent. Addicted to Murder was the first micro-budget film ever to be widely distributed through the Blockbuster Video chain.
