Mindhunter, Season 2 (2019)

Amid sweeping changes at the BSU, Holden deals with severe repercussions from his close encounter with Ed Kemper.

The second season successfully remains as excellent as the first and expands the dimensions and social implications in its exploration of the criminal mind.

Mindhunter, Season 1 (2017)

In the late 1970s two FBI agents expand criminal science by delving into the psychology of murder and getting uneasily close to all-too-real monsters.

Excellent TV series manages to create 70s period with atmosphere, and the plot centers more on the development of forensic psychology than on crime detection,  but is nevertheless suspenseful. Cameron Britton's performance as the serial killer Ed Kemper is especially chilling.
