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: The "original" versions are 4x3 letterboxed... . The "original" versions are 4x3 letterboxed... For anyone with an HDTV or widescreen regular TV, these DVDs are a major disappointment. The original versions are matted from their original 2.35:1 aspect ration for 4x3 TVs, so they look like crud on an HDTV or other widescreen TV. They appear to be made from the same transfers used for the laserdiscs. The other versions, from 2004, appear to be identical to the DVDs previously released
Example Output: NEG

Example Input: It killed an evening that needed to die, anyway. . Thank God I borrowed this one from the library! Every time I saw a spinning propeller I thought of what my WWII veteran parents must be doing in their shared grave if they saw any of this crap through my eyes. I couldn't even enjoy the battle scenes because of the technical anomalies and anachronisms. It did keep me watching for the entire three hours just hoping it might get better and it finally did when it stopped
Example Output: NEG

Example Input: Not for the half-hearted Eurythmics follower like me... . I must admit that virtually as soon as I bought this DVD (out of curiousity because many other reviewers are in the "gotta see them live" camp) I wondered if I'd done the right thing; when I played it I SO much wanted to justify my purchase but alas cannot; there is energy, yes, but little variety - all musicians apart from Dave S are subordinate & the performances, to me, are formulaic; I almost cut it off after the first 6 tracks but skipped forward to "Walking on Broken Glass" & "There must be an Angel" &, thankfully found some comfort in the familiarity of these & the (few) songs which followed. Bottom line: fine for true fans but not for the half-hearted
Example Output:
NEG
