Yep. You should see it, even if you don't usually get Netflix, it's not too expensive to do for a free period or discounted period, if they still do promotions. With your deep interest in these things, you could definitely use those shows and they used to also have Forensic Files as well. A fictional series based on the original FBI agents who started the entire FBI profiling area of expertise to catch serial murderers is also on there: Mindhunters. I have read a few of the books by some of those original profilers as well and though the show does develop personal lives that are probably not accurate or real, the stories of how they approached serial rapists and murderers is based on real interviews and cases. There are also some Ted Bundy stuff: Conversations With a Killer: The Ted Bundy Tapes. A mini-series based on Ted Bundy from the perspective of his former girlfriend (Extremely Wicked Shockingly Evil and Vile) is a Netflix original and also pretty damn accurate as I discovered from reading about the case and a new documentary from her perspective as well as his victims' families' perspectives, etc on Prime, as well as her updated biographical account of Bundy. Catching Killers is a newer one I've watched on Netflix. Other individual crime series on there that can teach all kinds of things are Why did you kill me? and Evil Genius. One uses social media to catch a murderer, the other shows some truly demented team-oriented crime and murder that was finally caught.
ID Discovery also has a series, Signs of a Psychopath, which is really good for nailing down what psychopathy really means. There are no psychiatric/psychological diagnoses for psychopathy and sociopathy (see the DSM V manual). They are criminology terms to explain, in more layman's or law enforcement/profiler terms, the type of criminal being assessed. That series really made clear to me the difference between psychopaths and sociopaths...which can also in turn help determine what kind of behavior, motivation and logic to expect from a suspect.
