Reviewers from The Chicago Sun-Times noted that the series is less about the killer, David Berkowitz, and more a tragic profile of investigative journalist Maury Terry , whose life was derailed by his obsessive pursuit of a multi-killer theory.
Some critics, such as those at RogerEbert.com , criticized director Joshua Zeman for appearing to believe Terry’s unproven claims about a nationwide Satanic cult without providing enough pushback or counter-evidence.
According to reviews on IMDb , many viewers found the series gripping and appreciated the detailed breakdown of the police investigation's inconsistencies, even if they remained skeptical of the broader cult conspiracy.
Critics generally praised the "grimy aesthetic" and the meticulous use of historical NYC footage, which effectively conveyed the terror of the late 1970s. Audience Perspective
