A fast-paced, compelling documentary that's sullied by an asinine "maybe YOU'RE complicit too!" final thesis that comes out of nowhere, insults its own audience, and makes the filmmakers hypocrites.
You made a documentary about a narcissistic murderer, not the victim, and then have the audacity to turn around and complain that the media "never talks about the victim, only the attention-seeking killer" as if that's the audience's fault. And then you called your documentary "Don't Fuck With Cats", focusing on the animal abuse and not the human victim. Hypocrisy at its finest.
Clip that ham-fisted, idiotic final 2 minutes and the documentary is a solid 8/10. That nonsense knocks it down to a 6 at best.
P.S. The fact the police have no idea how the internet works is a catastrophic failure (one of many) in our modern justice system.
