Example Input: I did not enjoy this video or find it informative. I thought the video was very boring and only watched half of it before I tossed it. Also, I bought this because I was having my first child and didn't know what to expect during labor but once you go into labor the nurses tell you everything to do so the video was a total waste. Also, the lady on the video is very annoying. I felt embarrassed for her.
Example Output:
Negative
