Each episode of Devil in Disguise focuses on one of Gacy’s victims, giving insight into their dreams, fears, and challenges. The series redirects its lens from Gacy’s notoriety to the lives he shattered, humanising them in a much more intimate way and recognising the systemic breakdowns that let those crimes go on for so long.

Reviews celebrate Peacock’s chilling limited series for its empathy, depth, and emotional power — a standout entry in modern true-crime storytelling.
