Instruct: Classify Amazon reviews into positive or negative sentiment
Query: I'm sure there are better books elsewhere

The book provided a fairly decent foundation for the concepts it presents, though I feel as though it does so in an overly wordy and diffuse manner. The authors frequently make sweeping statements about a general topic with little to no evidence; indeed, little to no evidence even exists for some of the generalizations made. Similarly, the authors frequently pose what appears to be a significant question at the beginning of a section and then do little to answer it, instead jumping from topic to topic as if to say "look how much stuff we know!" I know I have a bias in coming from the physical sciences, but I believe students and instructors can find a clearer and more concise overview of the material in another book.
