I dont usually recommend TV series, but mindhunter is an instant hit. here is the plot

Set in 1977 – in the early days of criminal psychology and criminal profiling at the Federal Bureau of Investigation – Mindhunter revolves around FBI agents Holden Ford (Jonathan Groff) and Bill Tench (Holt McCallany), along with psychologist Wendy Carr (Anna Torv), who interview imprisoned serial killers in order to understand how they think with the hope of applying this knowledge to solving ongoing cases.

The actors are not well known but the acting is good, the story line is captivating and serial killers!!!what more can you want!!

It's on netflix and kodi!!!Only one season but you will end up begging for more!!
