What Memories of a Murderer: The Nilsen Tapes is like, and who it is for
What it is like to watch
Watching this documentary is a stark, claustrophobic experience. The pace is deliberate, allowing the unsettling weight of Dennis Nilsen’s own voice to dominate the soundscape. Unlike typical reconstructions, the intensity here is psychological rather than visual, rooted in the cold, matter-of-fact narration of atrocities. It feels deeply voyeuristic, as if the audience is eavesdropping on a private, recorded confession that never seeks forgiveness.
Who it is for, and who should skip it
This is intended for true crime devotees who appreciate primary source material and clinical examinations of psychopathy. However, casual viewers or those sensitive to graphic verbal descriptions should skip it. The film is undeniably grim and lacks a traditional moral arc, which may leave some viewers feeling hollow. One honest caveat: the relentless narcissism of the subject can become repetitive and deeply draining over the runtime.
The right evening for it
It suits a quiet, focused evening when you are prepared for a dark, intellectual dive into human depravity. It is best watched when you have the mental capacity to process a truly uncomfortable and authentic narrative.
