Does anyone else find this show frustrating?

I really love the premise of the show, and overall I thought it was well written, researched, acted and directed.

However I found some of the shows writing very frustrating, and greatly to its detriment.

The primary conflict/ theme that the show seemed interested in exploring was the morality of sympathizing and empathizing with crazy murderers. ("IS THERE METHOD IN THE MADNESS?")

However this theme which dominates much of the plot progression, characterizations and dialogue is undercut by the fact that audience:

a) already has an interest in serial killers, and therefore don't find it morally objectionable to be fascinated by them (and are deeply skeptical of the potential psychological harms of that interest)

b) already know that understanding their motivations and psyches will ultimately prove very useful in the future. (Q: Is there method in the madness? A: Yes, and even calling it "madness" is stupid.)

So the (supposed) dramatic tension created by Holden "crossing the line" is ultimately not very interesting? Yet the show consistently focuses on this instead of actually getting into the psyches of the serial killers (the actually interesting part of the show!)

And in order to play out this tension in the dialogue, Holden must become totally unable to communicate with his colleges, and in turn they must become totally incapable of empathizing with him. So much conflict in the show is created artificially through the characters' inability to communicate and compromise like smart, professional, people?

(Because we all essentially agree with what Holden is doing, the writers have to turn his character into a reckless, stubborn egomaniac, in order to maintain the supposed grey morality of what he is doing.)

This artificiality is further emphasized because our main characters: a) all essentially agree about what they are doing and b) are supposed to be in the business of understanding other peoples motivations and personalities.

There is a difference between the conflict coming externally (everyone else vs our main characters) which is an interesting wrinkle in the historical setting of the show, and it being the primary conflict between main characters which dominates the screen time. The writers seemed so preoccupied with milking conflict from every relationship in the show, that they transformed all of the main characters into stubborn assholes who seemed to vehemently disagree about minutiae.

TLDR: I think the show is frustrating because it keeps pushing its least interesting aspects (Is there method in the madness? How far is too far? Does empathizing with serial killers make you as bad as them?) in-front of its most interesting aspects (Serial killer psychology, a historically interesting plot, good characters)
