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: Like many who have found this camcorder, I liked the canon name and bought based on Canon and value. It was a mistake because I don't feel I should have already used up the life of this camera yet. If you go to several discussion groups you will see it has several issues with the deck, i.e. "transport". Just google zr20/40 etc. and "eat tapes". Suggest you try Sony or Panasonic.
A:
Negative
