I am really into this new show Mindhunter. It is a period piece in the 70s about the discovery and classification of serial killers by the FBI. I'm normally not into crime drama as I find I find they are generally overly gruesome these days or unrealistically suspenseful, but my wife and I took a gamble on this one and started watching it.
Holy hell this show is well done. Incredibly talented actors and great direction all around. All the creepy material comes out in descriptions from the serial killers themselves, and subsequent analysis by the investigators. The understated acting is amazing, and the casting of the serial killers is incredibly well done. This one isn't for the faint of heart, but most of the discomfort comes from their completely disconnected and distorted view of reality.
Anyways, this one was a total surprise pick and keeps me coming back for more, had to share :)
