Is the Movie Knock Knock Scary?

Are you a horror movie enthusiast looking for your next scare? Have you heard about the 2015 psychological thriller “Knock Knock” starring Keanu Reeves but are unsure if it’s worth watching? In this article, we’ll take a deep dive into whether or not “Knock Knock” is truly scary.

Plot Summary

First, let’s talk about the plot of the movie. The story revolves around Evan Webber (Keanu Reeves), an architect who is left alone in his house due to his family being away on a trip.

One rainy night, two young women – Genesis and Bel (played by Lorenza Izzo and Ana de Armas) – knock on Evan’s door seeking shelter from the rain. As the night progresses, things start to take a dark turn as Evan begins to realize that these women have sinister intentions.

The Elements of Horror

Now let’s look at what makes a horror movie truly scary. There are several key elements that contribute to creating a sense of fear and unease in the audience:

  • Tension: Building tension through suspenseful music, camera angles, and pacing can keep the audience on edge throughout the movie.
  • Gore: Graphic violence and gore can elicit visceral reactions from viewers.
  • Jumpscares: Sudden loud noises or startling visuals can make viewers jump out of their seats.
  • Atmosphere: Creating a creepy or unsettling atmosphere through lighting, set design, and sound effects can contribute to an overall feeling of unease.

The Scare Factor in Knock Knock

So how does “Knock Knock” stack up when it comes to these elements of horror? While the movie does have its moments of tension and atmosphere, it falls short in delivering genuine scares.

One issue with the movie is its reliance on jump scares. While these can be effective if used sparingly, “Knock Knock” uses them excessively to the point where they lose their impact. Additionally, some of the jump scares are predictable and telegraphed, reducing their effectiveness even further.

Another problem with the movie is its lack of gore. While not necessary for every horror movie, gore can add an extra layer of shock value that’s missing in “Knock Knock.” This isn’t to say that gore is required for a movie to be scary, but in this case, it could have helped elevate some of the more intense scenes.


In conclusion, while “Knock Knock” may have some elements of horror such as tension and atmosphere, it ultimately falls short in delivering genuine scares. Its excessive use of predictable jump scares and lack of gore make it a less than thrilling watch for horror fans. However, if you’re a fan of psychological thrillers or enjoy Keanu Reeves’ acting, you may still find something to enjoy in this film.
