Teacher: 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).
Teacher: Now, understand the problem? If you are still confused, see the following example:
My Kids Love It . My 2 & 3 year old love this movie. They love to dance to the music. Garfield is so entertaining. This was a great buy.
Solution: POS
Reason: The overall sentiment of the review is positive as the reviewer refers to the dvd with positive expressions such as 'love it', 'entertaining', 'great' etc. Hence, the label is 'POS'.

Now, solve this instance: Every puzzle has its pieces . The best psychological thriller I have seen, this movie will leave you in shock by the end. Smart and cleverly written by Aussie's Leigh Wannell and James Wan, and directed by the latter, this movie breaks down all the boundaries of on screen violence. Starring Wannell himself, his character Adam wakes in a bathtub in a room with no lights. He calls out for help and hears a strangers voice, the lights come on revealing the two chained and shackled in a grimy, abandoned, windowless industrial bathroom. And so the game begins... The two prisoners are victims of serial killer Jigsaw, well he really isn't a serial killer as we find out. He puts his victims through a dangerous game to test their will to live, and its up to the victim if they live of die. This movie is one hell of a rollercoaster ride which will appeal to fans of both horror and psychological thrillers. It was voted one of the most scary films of all time, and while I didn't find it too scary, its the reality that these crimes could happen to anyone that is most frightening. Filmed in only 18 days, most of it filmed in a warehouse, this is quality filmaking by a young up-and-comer. Many studios knocked this back which they surely must regret as it went on to gross over 55 million dollars. Buy it if you liked Seven, Kiss The Girls, The Bone Collector and Red Dragon
