Instruct: Classify Amazon reviews into positive or negative sentiment
Query: What's all the fuss about?

I am a writer of fiction and non-fiction, and was curious to read this book for myself after seeing all of the great reviews. I found the author's condescending tone to be a major irritation throughout the book. I also found the information to be condensed and not useful. If I want to create a character who is a serial murderer, I can research it myself instead of getting a brief checklist of character traits. This is the least helpful book on writing that I have read this year.
