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 recommended . My husband and I were very disappointed with this DVD set.  One DVD contains an "action documentary" with music - we did not like that DVD.  We thought the second instructional DVD is mediocre and might be helpful if you are a complete novice.  The treatment of subjects is in our opinion pretty superficial overall.  There is little breakdown of technique.  There is minimal race footage, which is helpful to watch to learn by watching experts.  Parts of the footage seemed recycled - we heard very similar discussions about ski wax in the separate "tuning" and "equipment primer" sections.  You cannot watch the DVDs straight through as they dump you back into a main menu after you complete a scene.  So you must frequently fiddle with the controls to select scenes to watch.  That feature is helpful if you want to access scenes easily perhaps but we did not like it.  I am not usually a complainer but we were so disappointed with this set that I wanted to put up a review.
Example Output: NEG

Example Input: I walked out of the Theater on this flick.... . I was a Sophomore in HS and went to this cartoon with my cousins, What a mistake! I walked out and sat in the car till it was over.  It was awful.  I think it is sick that even grown ups think this is so amusing to watch cartoon characters have sex.  I wouldn't even rate it a "1" star.  More like Zero Stars
Example Output: NEG

Example Input: Not for DVD aficionados . I'm rather upset with the technical quality of this DVD.  Grindhouse rereleased this disc exactly as it was in 2000, without so much as a 16x9 animorphic upgrade.  This is certainly not worth the $20+ dollar price tag Amazon.com has right now
Example Output:
NEG
