This man is a true psychopath and monster and the case is very disturbing. The actual documentary is quite well done, I'd give it a 6.5/10. I'm not sure exactly what was missing, maybe an interview with someone who knew him and some more information, but the police officers did a great job and I really felt for them. I wouldn't mine a follow up once he's up for parole next year.

Before getting this Documentary I read a few articles on this case and the psyche of Paul Denyer was not well described but that's where the documentary shines. The chilling interrogation footage and choosing this serial killer to light to other parts of the world was a great decision by Stan. By the end this does leave you scarred as to how emotionally insensitive a human can be and how psychopathic mind begs for attention and their obscene trophies. My only complain was I wanted to learn about the letters and transgender area needed a bit of elaboration and the end didn't work right for me. Rest the documentary is something you should really watch for some good insight into this Australian Serial Killer.
