- Anvilicious: The first movie doesn't even try to be subtle with its message about date rape and STDs.
- Complete Monster: Brett "BJ" Jaffe is a misanthropic Serial Rapist and a carrier of the zombie virus who seeks to bring about the end of humanity. He seeks out women and violates them, infecting them with the disease and causing them to deteriorate both mentally and physically over the course of three days, after which point they reanimate, and he lets them spread the plague further. BJ is introduced in the first movie giving a woman a spiked drink and raping her, leading to her descent into madness and zombification. Later, he's shown to have claimed many more victims. In Phase II, he infects a prostitute and chain her up in his basement. BJ stalks a witness to one of his rapes, threatening to bring harm to his family and to him. When the witness is hospitalized, BJ straps a bomb to his own chest and tracks him down, threatening to blow up the hospital, and gunning down a few cops, patients, and doctors in the process.
- Foe Yay: BJ gives off this vibe when he first confronts Riley. And given the horrible results of his disease, it doubles as No Yay.BJ: Riley, Riley, Riley. I've been watching you. You and I have a relationship now. I gave it to Sam. My own little Typhoid Mary. Sam gave it to you. Part of me is flowing through you.
- Harsher in Hindsight: Near the end of the second movie, BJ straps a bomb to his chest and goes on a shooting spree inside a hospital. This is remarkably similar to the modus operandi of the ISIS terrorists that attacked the Bataclan theater in Paris.
- Moral Event Horizon:
- Sam strangles Nikki and only gets worse from there, murdering Alice and having sex with Riley with the intention of spreading the virus to him.
- While BJ was always a disgusting person and wanted to wipe out the human race solely for his need to feel emotion, threatening to blow up a hospital along with himself is pretty low, even for him.
- Narm: The Big Bad's initials and the nickname he goes by are B.J. Immature humor aside, it doesn't help the first film seem any less blatantly Anvilicious.
- Nausea Fuel: Let's see: bloody urine, a man having sex with a woman who's rotting away and has maggots crawling in her genitals, an infected woman scratching violently at her rash and peeling off skin in the process ... are you getting the picture yet?
- Squick: If it isn't Nausea Fuel, then any of the Body Horror sequences in either movie is definitely this.
YMMV / Contracted
