One core reason a person who isn't trained to use this manual would rate it below par is that, it's not a collection of mental disorders for self-evaluation; this is purely professional material for licensed Clinicians and related practitioners.
This is a guide to helping people who need to reach their full potential after being battered by life. And people are given specialized training to help, using the MSM-5 as a guide.
So, you are NOT supposed to read as a non-member of the said profession, let alone post a review. And I must add that it's a grand manual!
