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: A delightfully funny story! A wonderful graphic novel that gives us a cat's-eye view of the Sephardic Jewish community in Algeria and then the Algerian community in Paris in the early 20th Century. It's a love story. Very funny and endearing. And the hero is a cat! This is a must for Joann Sfar fans.
Example Output: Positive

Example Input: A disgrace to both REM and the work of good quartets. The idea is enticing, but the quartet's execution is awful. Truly terrible. Dull. Choppy. Uninteresting. Same. I'd say boring, but I can't stand to listen to it long enough to get bored. It's so bad I was compelled to log onto this website just to see if I could get my money back. I see the quartet doesn't even have a name -- I can understand why. It's advertised as just "The String Quartet Tribute to R.E.M." and it lists the players. Maybe someone else could do better, but I doubt it, as the arrangements are bad too. Sorry to say it, but this CD is truly awful!
