Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Disappointed!!!

After reading the online reviews (many of which were positive) I decided to purchase this book to read while on vacation. I have to say, I was very disappointed! I couldn't believe that it had been given such great reviews - the book was boring, the characters were underdeveloped and lacked substance. There was nothing believable about the novel. I hope Michele does better with her next novel.
