I'm not the biggest Rob Lowe fan, but he's great on that show and I think that when he joined was when it really hit it's stride, and also when it declined after he left.
I just binged Mindhunter. I think the show is not really meant for people who are very familiar with the subject matter, because a lot of people didn't get it. Like they don't know who the dude they keep showing at the beginning is. I don't think that it's meant to be a mystery, but people had some crazy theories.
I won't spoil anything, but if you didn't catch it, the show itself gives the information as to who he is and how he connects to the main story, it just gives it as clues and background information.
People also complained that the couple had no chemistry....that was the point! They are both going against their own inclinations in order to have what they think is a normal relationship. The major theme of the show is given in a psychology lecture about how people's behavior is a performance designed to conform to what they think everyone else believes is "normal." This applies to all of the characters on the show, and is the thing that connects the real normal people with the psychotic killers, and allows them to understand the mind of the killers.

Holden Ford/ John Douglas is a psychopath and he gets off on catching killers the same way that they do on murdering people, and he would probably be a murderer if he wasn't an FBI agent.
After watching the show I looked in my library and was amused to see that I actually have Mindhunter the book in my collection, but I had forgotten.
Spread out all around us is a petrified world, a world of Things, where we ourselves, our gestures, and even our feelings figure in as Things. Nothing can belong to us as truly our own in such a landscape of death. Under commodity occupation the most concrete truth about everything is the truth of it's infinite replaceablity.
