Query: Profoundly disappointing

I am a psychiatrist, and hoped to glean some insights into OCD that would enhance my work with patients. I also hoped to be amused, since the book's advance praise suggested the book made good points while being humorous. I was so disappointed. The book is an easy read, but becomes boring quickly. The writing is rather drab, and the potential of this subject is lost. The writer seems to have little insight into her behavior and has little to share and teach others. A waste of $12.
