There is huge irony in the fact that, notwithstanding the completely inappropriate title, this 3 part doc has almost nothing to do with cats -- and everything to do with how a bunch of internet geeks who had never met tracked down a truly diabolical Canadian serial killer. Even those who did not ""like"" the movie agree it is one of the most compelling stories ever put to film -- once you start, you will binge the 3 parts in one sitting. It is also obvious -- painfully obvious -- that the police in multiple jurisdictions were always on the back foot throughout the chase. It was the internet geeks who did the heavy lifting -- they even predicted the murder before it happened, and were ignored. And it was the manager of an internet cafe in Berlin, a self-proclaimed news junkie, who recognized the suspect on sight, in a heartbeat, and called the police, even while the international police still thought he was in France. Astonishing and unforgettable.
