Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

[Q]: If you paid for this product, you overpaid. Granted, the original, out-of-print dvd of The Bikini Carwash Company sells for exorbitant prices, so my suggestion is to just download it for free through torrents and cut the video pirates and video scalpers down to size. If anything, buy the European PAL version, which is also uncut and uncensored, and available on the North American Amazon as well.
[A]: Negative

[Q]: If you are not in really good shape this is a great product to get ready for P90X. It does get kind of boring because you are doing the same workouts every other day, but they do work. It is only about 30 mins but it is amazing how well it works.
[A]: Positive

[Q]: In a word, Lacking. Her style of writing left me unable to appreciate the underlying story which, as a result, I found rather vacuous and inauthentic. So much so that I felt compelled to come write a review of this book so others might avoid making the same mistake I did. No offence Patricia.
[A]:
Negative
