I give it five for five when talking about his personal experience, but drop it by one because McHugh doens't include references and scientific literature to address his points. It's meant to be an autobiography of a weird time in the history of psychiatry, but I always find books more convincing when there's links to source material. Very readable, very interesting, but not quite as convincing as I'd like it to be.  

An absolute masterpiece. McHugh demolishes the dangerous psuedo-science that has motivated modern psychotherapy, specifically the Freudian nonsense that spawned the "repressed memory movement" over the past two decades. Hopefully McHugh's important book will help us close this dark chapter in the history of modern psychiatry.
I cannot recommend this book highly enough.
