That title is what got my attention as I was looking for something compelling to binge-watch. It’s called “Don’t F**k with Cats: Hunting an Internet Killer”
The basic premise is a sicko posted a video of himself doing something deplorable to a kitten that results in its death which is followed by self-proclaimed “internet nerds” trying to piece together clues to find out who and where this person lives. Compelling true life series (it’s only 3 episodes).
One more note worth mentioning is the real-life challenge with the great difficulty the nerds have in gaining credibility with the police as the nerds got involved in trying to solve the case months before police were interested makes for edge-of-your-seat, yell-at-the-screen, quality tv watchin’.
