Example Input: Review: We've been served - a terrible film.Okay, I'll admit that since I'm white and have had no practical experience in the "competitive world of step-dancing," I might not exactly be an authority on this type of film. On the other hand, I do know a bad motion picture when I see it.And, boy, have I just seen it.Filmed in Low-Budget-Vision and directed by Ian Iqubal Rashid, ("A Touch of Pink"), "How She Move" tells the tale of how important it is to follow one's dreams - even if those dreams include bopping around to loud, irritating hip-hop music and speaking dialogue the average person would not understand if he or she had an international translator.I'll try to give a small synopsis of the "plot." First of all there are two actors that look like LL Cool J who work in an auto shop in Toronto (the Mecca of racial diversity), but still have time to practice dancing for eight hours a day. There are a few other guys in this "crew," including a token white dude and a guy that looks like Denzel Washington in "Malcolm X." There are also two women in the movie - one resembles Serena Williams and the other looks like Geraldine from the old "Flip Wilson Show." One of these ladies was kicked out of a private college because her parents spent all of her tuition on a drug-addicted sibling. The other girl, a member of Salt N Pepa, no doubt, is just plain no good.There's another guy who looks like Eddie Murphy's Buckwheat, while still another actor who's a Huggy Bear knock-off. These guys are rival step dancers. Evidently, this activity is very hard-core in the 'hood, and they are all practicing for the big "Step Monster" jam in Detroit.Since I was unable to understand 90 percent of the dialogue (perhaps some subtitles would have been useful, as in a Bergman film or that one music video by Snow), it's hard to explain what happens, other than there's a lot of arguing, the Serena Williams girl (who never smiles, by the way) becomes a freelance stepper (moving from group to group), there's some step-dancing and a lot of irritating hip-hop music.It's a typical rags-to-riches story; sort of like "Rocky" with a really bad soundtrack, "Rudy" with annoying rap music in the background, "Cry Freedom" without the laughs. But why does a film - which could have made a big impact on black audiences - have to contain drug addiction, bad parents and a title that sounds like a first-grader saying the phrase, "How she moves"?I was "moved" by this movie, however. Moved to leave the theater as quickly as possible. Question: is it a positive review?
Example Output: no

Example Input: Review: Both my friend and I thought this movie was well done. We expected a light hearted comedy but got a full blown action movie with comic thrusts. We both thought that this movie may have not done so well at the box office as the previews lead us to believe it was a comedy. I was impressed with the supporting actors and of course Dave Morse always puts in a terrific acting job. Most of the supporting cast are veterans not first timers and they were solid. We both felt that the writing and direction were first rate and made comments to each other about buying this movie. If you don't buy rent it for a good time. Question: is it a negative review?
Example Output: no

Example Input: Review: After having seen a lot of Greek movies I feel very suspicious against most of them. But after watching this I felt astonished. The movies is great without a big try. You cannot claim that the screenplay is so great or the photography is perfect or something technical. It's a real story and it is happening in Greek rural areas in places forgotten from God. The movie is like a punch in the stomach and I would really wish that things are not like this. It obviously talks about the xenophobia of the Greek people (the ignorance)to anything different. The problem of this guy is not that he is an ex-convicted. The problem is that he is not one of these people. He is different and they do not want them (that's why all the good things he is doing turn boomerang to him). And also speaks about the apathy of the people, because there are some people who are against the hunting of the King, but they do not dare to say their opinion. In the end you can clearly see the hypocrisy of the society being religious and trying to act like God says, but at the same time acting so unfairly to the King. This shows how easily people rationalize their feelings or their beliefs according to the established system. In the end you can have a positive lesson from this very bad story, meaning that you can understand and be part of this society only if you want to become one of them. If you want to remain different and even alone, you are lost (and it is not far from reality) I think it is tragic that the story is real and this should be a bell for everybody. No comment for the main actor because he is already given an award and I believe that his play was great. Small comment for Hatzisavvas (plays the policeman), he is like a dinosaur, he has played a lot of roles and I'm sure that this role for him was very easy but he plays it so great that you cannot deny him a big bravo. I definitely recommend this movie to anybody who wants to see a good Greek movie. Question: is it a negative review?
