Example Input: I think the video was really good, im a nurse so i know most of the information already but it will hopefully help my husband. I think my husband preferred the video to an actual class. I mainly chose to use a video because of my schedule. The only thing I would have liked to see a little more was ways to help deal with the pain- like more breathing techniques. Overall I think it was good and would reccomend it.
Example Output: Positive

Example Input: The hard cover reprint edition offered by Amazon and others is incomplete. It contains Part 1 only. Note the page count (208) and compare it to the trade paperback versions (310-324 page count).Avoid this edition.
