I'm a true crime junkie and of course have seen most documentaries on Gacy. This one though, I hadn't heard any of these audio clips before and it really shows the evil of the man. In most footage and interviews Gacy had a mask on. These tapes are something else though. There is one point in episode three where he laughs and if it doesn't send a chill up your spine, nothing will. Probably the best Netflix documentary series I've watched so far.
