Neil Strauss's "The Game" is what cemented my nagative views about PUA's
For me that book shone a really bright light on a community, and its two types of citizens - the "wantrepreneurs" who would try to trick their way to success, and the really serious guys who changed their whole lives to succeed.
I saw obvious parallels between them and the startup community. And, yes, I suppose, serial killers and any other community who wants to succeed.
Curious as to what you found was negative and why.
In my opinion, diluting a relationship down to scientific behaviors and applying that to your relationships is dehumanizing and disingenuous. I don't want to associate with people like that.
