In this task, you are given product reviews about dvds. The goal is to classify the review as "POS" if the overall sentiment of the review is positive(the reviewer is satisfied) or as "NEG" if the overall sentiment of the review is negative(the reviewer is not satisfied).

Example Input: Not what was promised . Original Review: I could never get the edition with the Leather Jacket as promised. After contacting Amazon 3 times and sending back the same version 2 times without a Leather Jacket I gave up. Even their customer service department said I would never get the correct selection. I guess what you see isn't always what you get. I'm sure the actual movie is fine. I haven't opened it yet as I assume it is new and shouldn't have any scratches. Maybe I should check that, too! Follow-up Review: Judy in Customer Service called me and said she made a special effort to track down a copy of Grease in a leather jacket for me and I could send them back the old one in exchange. She was very kind and I give her Kudos for being so involved. As promised, I got my Grease in the leather jacket and my husband is impressed with his gift! I would give this 5 stars now, but it wouldn't let me change it.
Example Output: NEG

Example Input: 0 STARS: These movies are worse than the original. . These movies are just total nonsensical rubbish about mutated babies. From a horror movie fan's perspective, I remain completely unimpressed with the merits of these films and that includes the original, "It's Alive". The only thing about babies (mutated or not) that scares me is having to change their diapers...it stinks and this entire trilogy stinks too! What a worthless...waste
Example Output: NEG

Example Input: Great Series . Lucille Ball's second TV Show "The Lucy Show" doesn't seem to come close to her first, the extremely popular "I Love Lucy", in amount of reruns syndicated on television. This is a shame since the quality of the two shows are very similar. In the series, Lucy stars as Lucy Carmichael, a zany secretary working in a Hollywood bank for her stodgy boss, Mr. Mooney. Lucy's less-than-efficient secretarial skills and wacky hijacks frequently infuriate her boss, but somehow she is loyal to him not matter what. The five episodes included in this DVD feature some famous guest stars including Carol Burnette (playing Lucy's librarian roommate Carol), and John Wayne, Milton Berle, Ruta Lee, and George Burns. Like in "I Love Lucy", Lucille's character fawning over the movie stars is very amusing and even though the series was made a decade after "I Love Lucy", she still does much of her physical comedy pretty well. The picture quality of the episodes is not the best and the menu navigation for the DVD is somewhat confusing, but those problems are not bad enough to distract from the shows. While its not quite as good as Lucy's first show, it's still a great show and worth a look if you enjoy "I Love Lucy" or Lucille Ball
