[custom_adv] When heading to London as a graduate student, I was required to get a physical and a tetanus shot prior to making the move. When I made the mistake of announcing the tetanus shot on my personal Facebook, people misunderstood and thought I had stepped on a rusty nail or some other dastardly deed. [custom_adv] The film opens with Chloe and her boyfriend Danny (Jordan Bolger) being inexplicably drawn to a house nearby where a woman named Mary Aminov used to live. [custom_adv] Convinced that, years ago, she kidnapped and killed a boy who lived in their group home, Chloe and Danny harassed her long after the police decided they had no case. They drove her, it seems, to suicide, and now a legend has flourished that something demonic lives in her house. [custom_adv] If you knock twice on the door, it will come to get you. Danny, of course, knocks twice. And then the demonic witch comes to get him. In terror, Chloe flees to her mother’s home—even though she had earlier brutally refused Jess’s plea that Chloe come live with her. [custom_adv] But the witch pursues Chloe even to her mother’s house—and so Jess ends up fighting for her daughter’s life. [custom_adv] One of the strengths of Don’t Knock Twice is that the story, at several moments, doesn’t play out as you think it’s going to. There are some genuinely surprising twists. [custom_adv] One of the weaknesses of the film, however, is that there are perhaps too many twists; the pacing is off, and it seems things always happen too soon, too suddenly. These twists, along with moments designed only for shock value, overwhelm the development of both character and story. [custom_adv] Neither are fleshed out fully, and their depths remain untapped. And that includes not only the main characters of Chloe and Jess, but also a seemingly more minor character, Tira (Pooneh Hajimohammadi), who turns out to be much more important than she appears, and who is unfortunately given no backstory at all.
