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

Wish I had read these reviews before I picked up the book! I agree that the dialogue and characters were contrived and the ending lets the reader down. The poor reader spends all this time waiting to see what happens and ends up with having to fill in the blanks on their own. Very unsatisfying. Too bad...the subject is one worth exploring in a meaningful way. Cook missed his chance.
