Melissa Camacho Common Sense Media Jan 27
3/5
True crime fans will appreciate the lengthy and detailed narrative, but The Hillside Strangler is as much an indictment of California's criminal justice system at the end of the 1970s as it is the killers. Go to Full Review Read all reviews

Vkk U @RT65946548 Jan 30 EXCELLENT direction, Immersive archival footage, PROCEDURAL POLICE Format documentary - not some contrived sensational garbage focused on the "victims" but a real crime/police documentary with tons of photos, grainy film, police interviews, great sound track, some sound effects but I had to take 1 star off for some stupid over-the top BONG type sound effects, some poor choices for background music, and a few cheesy editing techniques that lowered the quality level to TV-style journalism. Not Art but Primo True Crime Crack. See more Read all reviews
