Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Repeat, then repeat again

I am mistified at all the positive responses. The book basically says "think positive and good things will happen." Not a bad message, but the author basically takes that concept, runs it through a thesaurus 1000 different ways and cuts-and-pastes into a "book." No real thinking hear. And I am not a sourpuss - this is the first negative review I have given.
