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: What Were They Thinking? . Man, I don't know what the other reviewers of this movie were smoking, but it should be illegal!  This is, first off, a terrible DVD: 4:3 (full screen) format, with a dark, muddy picture.  Worse, the plot is typical, predictable, and poorly written.  Other than looking for glimpses of Teri Hatcher's body, sitting through this fiasco is a total bore.  I was also surprised at how bad Teri's acting was in this movie, since I've seen her do much better in things she was in previous to this.  That is probably the fault of the director, Erik Anjou, a third-rate director (at best!) who has done a total of two movies and one documentary.  Gee, I wonder why he isn't in more demand (NOT!)!    I can enjoy "B" movies, and bad movies, but this one is just so totally non-involving that it is not even good enough to laugh at.  I can't imagine that this mess was released on DVD for any reason other than to cash in on Teri Hatcher's current popularity, and to suck the cash out of people who are anxious to see a younger (29 year-old) Teri Hatcher nude.      Rent this, if you must, but, wow, there is no reason anyone should want to buy a movie this bad
Example Output: NEG

Example Input: The Prisoner - Complete Series Megaset (40th Anniversary Edition) . I am very happy with my purchase.  For over 25 years I have been wondering how this series ended.  I never saw the entire series just a few episodes.  It is a good show and I would recommend it
Example Output: POS

Example Input: Mediocre DVD Transfer; Average Sci-Fi Movie . For a 2-disc, director's cut, my expectations were perhaps too high for this DVD.  Nevertheless, I was appalled at the poor quality of the transfer.  The colors were dull throughout, and focus was frequently not at the beginning of scenes.      For the movie itself, I don't agree that it is holding up well over time.  At 25 years old, the movie just has limited entertainment value for people who aren't waiting for their beloved canceled TV series to be on the big screen.    There's no question that II and IV are the best of the series, but comparing it to other Star Trek original cast movies isn't putting the bar very high.    My interest in watching this again was just having finished Melville's Moby Dick, the final scenes of which Khan repeats liberally during the final space battle.  That said, I think Montalban was fantastic as the revenged-obsessed Khan and very evocative of Ahab.  However, Shatner's pretentious Kirk just becomes more grating as time goes on.  The original cast schtick just doesn't make for a compelling drama
Example Output:
NEG
