Mindhunter season 2 (Netflix)

I get to review a series that after seeing the first season, I really wanted to learn a lot more about the BSU that we followed during the Criminal minds TV series,  This is based on an FBI agent that was part of the creation of this unit.  We go into the second season that centers on the two major serial killers the BTK killer and the Atlanta child murders.  An intense and dark series but well worth the watch
