Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example is below.
Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: Even at the incredible Friday sale price of $4.99, I would not recommend these flannel sheets for purchase because of the very poor sewing workmanship. The stitches were very large, and also some of the edges were simply turned over once and sewn with a raw (easy to unravel) edge. The sheet would not hold up well after the first washing. I resewed all the edges of both sheets.
A:
Negative
