[EX Q]: 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?

[EX Q]: Review: I really liked this film when it was released, and I still do, because the storyline makes you feel hopeful about life in general, and people too...one of the things I like about the films of Lawrence Kasdan. In addition to the positive vibes from the film, there are other reasons to like Grand Canyon. For one thing, it has an outstanding cast...Kevin Kline and Danny Glover, for example. In my opinion, Crash, the highly acclaimed film that won the Oscar for best picture, was very similar to this film. The difference is that Grand Canyon leaves you feeling positive. Crash had the opposite effect with me; it was very dark. I would choose Grand Canyon over Crash any day. Question: is it a negative review?
[EX A]: no

[EX Q]: Review: Kusturika made it again. Another masterpiece. A coral comedy full of his own landmarks, with a frenetic rhythm and many glorious moments, we laughed and laughed, what a party! The music is everywhere, and also the shooting, the animals, the crazy bastards, sex and amazing gadgets and inventions, everything colorfully visual to entertain only. Pure cinema in essence. A wonderful experience to watch. And one is specially grateful since good comedies are so rare, and so wonderful. Well, this is one, and if you enjoyed Kusturica's previous films, you'll love this, although, as in all comedies, it is about a chemical reaction, and you have to be in the mood for it.
