A Deep Dive into Peacock's 'Devil in Disguise: John Wayne Gacy'

Peacock’s limited series Devil in Disguise: John Wayne Gacy premiered on October 16, 2025, and has already sparked considerable discussion among viewers and critics alike. This eight-hour drama takes a somber approach to the notorious serial killer, focusing on the psychological implications of his crimes rather than indulging in the sensationalism often associated with the genre.

The series, created by Patrick Macmanus, offers a unique perspective on the life and crimes of Gacy, played unsettlingly by Michael Chernus. Unlike other adaptations that may lean heavily into the horror of Gacy’s actions, Devil in Disguise opts for a more restrained narrative that prioritizes the humanity of the victims and the societal factors that allowed Gacy to operate undetected for years.

One of the most striking moments in the series occurs nearly six hours in, when Gacy finally dons his infamous clown costume. This moment, while iconic, contrasts sharply with the overall tone of the series, which has been described as “aesthetically chilly.” Instead of reveling in the chaos often depicted in similar serial killer narratives, the show presents a methodical and procedural exploration of the investigation into Gacy’s horrific acts.

The narrative unfolds through a tripartite structure that interweaves the police investigation, legal proceedings, and flashbacks to Gacy’s life and his victims. The focus on the victims is particularly poignant, as Macmanus delves into their backgrounds, highlighting the vulnerabilities that made them targets. This approach reflects a broader commentary on the societal conditions that contribute to such tragedies, moving beyond a simple portrayal of Gacy as a monster.

Critics have noted that the series does not shy away from the darker aspects of Gacy’s story, yet it handles these moments with a level of restraint. For instance, rather than depicting graphic violence, the series builds tension through psychological suspense, reminiscent of David Fincher’s Zodiac. The show’s creators have made a conscious decision to avoid exploitative shock value, instead opting for a narrative that emphasizes sadness and weariness.

While the pacing of the series has been critiqued for being somewhat draining, with some suggesting that a tighter six-hour format could have been more effective, the depth of character development and thematic exploration is commendable. The performances of the ensemble cast, including James Badge Dale, Gabriel Luna, and Marin Ireland, contribute significantly to the series’ emotional weight.

The finale, which jumps forward to Gacy’s execution in 1994, offers a reflective moment that could have served as a powerful conclusion to the series’ themes. However, some viewers may find the brief treatment of this pivotal scene somewhat disappointing, as it presents an opportunity for deeper exploration of the ethical dilemmas surrounding the death penalty.

Ultimately, Devil in Disguise: John Wayne Gacy stands out in a genre that often leans towards sensationalism. By prioritizing a nuanced portrayal of its subject matter, the series challenges viewers to confront the complexities of morality and societal failure. While it may not cater to those seeking adrenaline-fueled drama, it offers a thoughtful examination of one of America’s most chilling criminal cases, making it a significant entry in the landscape of true crime entertainment.
