I have not read a self-help book before, so it is difficult for me to compare to similar works. The title is catchy, so I gave it a go. Not being familiar with this genre, the writing style (and content) overwhelmed me and I re-read it to get a better sense of the material. In short, the author tries to do too much in too little space. Group therapy may work for AA; but for abusive relationships, it seems subjective. Maybe it is not group therapy; but more of a sermon approach.
The chapters are short and focused on certain aspects of psychology. Anecdotal stories occupy seemingly 50% of the book. They offer testimonial support to the author with very little else. A second reading excluding these stories makes it easier to focus on Brown's own words.
Brown covers a lot of toxic behaviors. Screwed Up People (SUP) rarely exhibit all of the behaviors in a toxic relationship. That means that Brown is running a gamut of different types of personalities and disorders. Readers seeking help will recognize some of these in their SUP and want more, only for Brown to change to something else. It is easier to picture Brown addressing an auditorium than a single patient reclining on a couch. This makes the entire book more like church than counseling.
Religion does play a role in the book. I do appreciate that bluntly states that she counsels against divorce except in certain cases of abuse. But the screwed up people may be siblings, children, friends, or employers. So, the book assumes that you will stick with the SUP. Religion does play a role in the book. It offers one of the most convincing arguments for prayer that I have seen: it is a sign of hope. Other sections have God sprinkled in. But only one chapter is devoted to faith. Again, the focus on that chapter is to retain hope for improvement in the relationship. The book does not drown in religion; but there is a preachiness to the book.
One reviewer claims that you, dear reader, are the SUP. I am not convinced. The advice that is given somewhat chaotically can be seen as common sense: set boundaries, stay focused, do not argue, disengage, change your own behavior - not the other person. Would a screwed up person read that and think 'that's me'? Maybe all of us are screwed up people. Brown does not say that.
Overall, the book is cursory and self-congratulating. Readers will certainly recognize toxic behaviors from their own lives. The actions Brown suggest may offer some relief. It all comes down to 'deal with it.' There is a chapter on when to end the relationship; but even Brown does not offer much enthusiasm in this chapter. She is usually upbeat and energetic. The overall tone and chaotic nature of the book reminds me of charismatic speakers who have terrible writing styles because their in-person strength does not translate into written words - James Burke and Simcha Jacobovici come to mind. It is an interesting book offering good advice.
