Example Output: POS

Example Input: Review of DVD not production . Firstly I have to say that this is not a Mobile Masterpiece production it is a BBC production.  The production itself is excellent, my favorite adaption of the Charles Dickens novel.  Unfortunately the DVD has been put together as if you are watching the production on television.  There is an introduction by an American presenter who states that what you are watching is a Mobile production.  This is tolerable but once you start watching you find that little icons appear on the screen as would appear on television (I think they are to inform the viewer that wide screen is available).  Finally, before the end credits of the first part, you get to see what will be in next weeks episode.  It would have been a simple matter to take the original recording as supplied by the BBC and use this one for the DVD.  For some reason the DVD producer decided that is was better to have exactly the same recording as was shown on American television.  If you want to get a copy of this production I would recommend getting one that was made for the British market
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
