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 up to History Channel standard . Sorry to say this two-pack is not up to History Channel usual high standard. DVD 1, on the Spartans (essentially leading up to Thermopylae) is good. However, DVD 2 is very disappointing. First of all, it has three documentaires, but in fact the first one ("The Odyssey of Troy") and the third one ("The Trojan City") are carbon copies of each other, which is somewhat of a fraud... Second, the information given by the historians is good, but the narrative itself is more than misleading -- it leaves the viewer with the impression that the Trojan Horse epic is part of Homer's Iliad. It isn't. Homer finishes the Iliad with the burial of Hector. It is in a "sequel" so to say, by Quintus of Smyrna, written many centuries later, that the story of the Trojan Horse is set down. It is also mentioned in other less complete writings, but certainly not in Homer.   To be fair, the second documentary in DVD 2 ("The Ancient Gold of Troy") is not bad, but does not correct the errors in the other "two" segements
Example Output: NEG

Example Input: Gore and Humor at the Opera. . Dario Argento's Terror at the Opera is simply about a psychotic hooded killer who terrorizes an opera diva whom he adores. The opera diva is Betty, a young singer who gets a chance to star in Macbeth when the original lead has an accident and breaks her leg. Her powerful (not) performances in Macbeth attracts the killer who randomly kidnaps Betty, ties her up and tapes a row of sharp pins under her eyes forcing her to watch him commit murder. Later on in the film we find out why he does this to her aswell as the killers secret identity. Terror at the Opera is more of a slasher rather than a horror, (as there is no real scary moments in the entire film) but still a good horror.    TATO is a very enjoyable horror/slasher. For the usual horror fanatic, it does deliver as it is gory and strangely at times very humorous. The camera work is great in this film as it exaggerates the gore by simply zooming in on a penetration of a knife or when the camera becomes the eyes of Betty, showing us what she sees through those sharp needles taped under her eyes. Apart from gore, TATO also has a mystery factor. As the film progresses introducing new characters and reminding us of old suspicious characters, the viewer soon begins to wonder who is the killer. And of course this does lead to a twist at the end.    With plenty of violence, mystery, thrills and humor, Dario Argento's well paced feature will not dissapoint. One bad thing I can say about this film is that the acting is quite bad, but that maybe the result of the terrible dubbing. However, Terror at the Opera is still an entertaining film and well worth a look
