Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Not worth buying

This might be a good title to skim if you are looking for ideas but there is very little practical knowledge included. This is especially absurd because we are told that the author has reviewed 50,000 manuscripts. If so, why do we get so little applicable insights from him. And for a guy who has, we are told, reviewed 50,000 manuscripts, the examples he gives are all from...movies! Not books, but films! What a waste.
