Instructions: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: My husband and I were not able to attend a birthing class, so the doctor suggested we rent/buy a video. We decided on this one, and although the 'teacher' was a bit corny it was helpful. I especially liked that you could fast forward and skip parts! All in all it was a worthwhile purchase and proved helpful to us both.
Output:
Positive
