Example Input: Dark Hero . A down and dirty Mel Gibson is fantastic in this film.  From his gravely voice, and the lack of a single smile throughout the film, he plays the part perfectly.  Porter is a man betrayed by his wife, his friend, and left for dead.  The entire movie involves him trying to get the money that was stolen from him back.  That proves to be not as simple as it seems, and soon corrupt cops, the mob, and Japanese gangsters are all out for him.  This one is worth the money
Example Output: POS

Example Input: The Magic isn't There . This is a fantasy film about a family of witches in modern times. The Owens girls are hereditary witches, any man who loves one is doomed to an early death. There is a scene where a woman asks for a love potion, this requires the sacrifice of a dove. Two little girls watch. Years later they're grown up. One leaves to live with her boyfriend. But the curse returns and a boyfriend is run over by a truck (never stand in the middle of a road). We see scenes where the neighbor kids yell "witch", as if to symbolize something.    Sally goes when Jillian calls her; she has a problem with her boyfriend. But Sally uses a "magic potion" to eliminate the problem. Now Jillian wants to undo what was done. [The film began to lose me now, it wasn't funny.] The spell goes awry, they bury their mistake. Then there is a scene where the ladies are all giggles. Later an investigator comes around looking for Jimmy. [The story drags again.] More scenes follow; they are not funny or scary or even entertaining. But a scene in the attic will wake you even if you're snoozing! They call some friends over to cast a spell to drive a demon out of Jillian. It seems to work, even if they don't use the standard issue witches broom. There is a sort of happy ending.    Sandra and Nicole are good actresses, but they can't cast a spell to improve the script of one of the worst movies I've ever seen. "Bell, Book, and Candle" is a funnier film, "Blair Witch" is a scarier film. This falls between the cracks.
Example Output: NEG

Example Input: Not a good film . What else is there to say?    The acting is mediocre, the story line is nearly non-existent, and the only redeeming thing this film has to offer is the somewhat interesting cartoons superimposed upon the original score.    The vast disconnect between the book and the movie is at its most evident when the film ends, concluding with a quote from Phillip K. Dick that has virtually nothing to do with what you've just seen and makes you wish that it (the film) did
Example Output:
NEG
