: Much of the tension in Des comes from Nilsen’s calmness. Subtitles emphasize the flat affect of his speech, ensuring that his most disturbing lines—often delivered in a low, conversational mumble—are not lost. This clarity prevents the audience from distancing themselves from the reality of his actions.

Ultimately, watching Des with subtitles transforms the viewing experience into a forensic study. It strips away the "entertainment" value of the thriller genre, leaving the viewer with the cold, hard words of a man who viewed murder as a tedious necessity of his existence.

: The subtitles capture Nilsen’s specific, often bureaucratic vocabulary. His tendency to refer to his victims as "objects" or "problems" is rendered in stark text, forcing the viewer to confront his lack of empathy without the distraction of background scores or atmospheric noise.
