Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Don't bother

This is one of the few books out of several dozen I have ordered from amazon that have been disappointing. The reason is now obvious to me: most or all of the other reviews have been written by Ms. Pinskey's friends and contacts. The book itself is uninteresting, generally fairly obvious, and heavily biased towards the US market. I would have given it two stars, but I am sufficiently angry at the misuse of the review system to want to introduce some balance. I just wish she'd put her energy into writing a better book instead of churning out this dull waste of paper and then pushing her associates into promoting it.
