Example Input: So it was long, and it was a slow read, big DEAL. Ms Lackey and cohorts have spun a gripping, involved tale of GREAT characters, involved PLOTTING and lots of FUN. I read for pleasure and this was a pleasure. I was always looking back to keep things straight, but it was FUN. I lost most of two nights sleep because I couldn't put it down. This team should write lots of sequels, and I WILL BUY THEM ALL.Be warned, if you pick up this book and start reading you will suffer. Yours friends and family will think you have run away, and you have, To Venice, where you can spend a ripping vacation in you mind. The lady has won me back.
Example Output: Positive

Example Input: My husband and I are expecting our first baby any day now. We opted to get a childbirth video versus attending a class. After doing some research and getting reccomendations from friends, I decided to purchase this video. While the information on the DVD is helpful and each segment is clear and easy to understand, the instructor presented it in such a way that made extremely painful to watch.The instructor continuously makes annoying jokes, mocks pregnant women and their partners, using the most unfunny and unflattering impersonations imaginable. Watching this woman's attempt stand-up routine was so uncomfortable that we often found ourselves fast forwarding through a lot of it. Please believe that neither me or my husband laughed during this DVD. Not once.I wish we had just gone to childbirth class.
Example Output: Negative

Example Input: The book which is a kind of a sequel to an epochmaking book by Alec Wilder is simply indispensable to anyone who is interested in the field. It is both intelligent and entertaining, as a book on popular music should be. Highly recommended.
Example Output:
Positive
