[EX Q]: Review: Grand Canyon is a very strange bird. It's a completely unique urban piece, where relating the entire plot would fail to convey much.It's central theme seems to be the inherent uncertainty life holds for people of every race, background and station. But to proclaim that THE theme of the film would be to horribly understate its scope. Similarly, to pigeonhole it in a particular genre is futile.The film has volumes to say, though likely different volumes for every viewer, and says it all in such a non-preachy way from so many angles, that in the end, i can't even define its central message for myself.Nevertheless, it does it's business with such laser precision; every prop, line of dialog, and bar of background music contributing to it's pervasive mood and powerful message, that i'm pleasantly surprised, and come away very thoughtful after every viewing. Still it doesn't feel at all stuffy. A sparkling film with a great cast and everything working. Question: is it a positive review?
[EX A]: yes

[EX Q]: Review: Midnight Cowboy made a big fuss when it was released in 1969, drawing an X rating. By today's standards, it would be hard pressed to pull an R rating. Jon Voight, who has been better, is competent in his role as Joe Buck, an out of town hick wanting to make it big with the ladies in New York City. He meets a seedy street hustler named Ratso Rizzo, who tries to befriend Buck for his own purposes. The two eventually forge a bond that is both touching and pathetic. As Ratso, Dustin Hoffman simply shines. Hoffman has often been brilliant, but never more so than in this portrayal. He is so into character that all else around him pales in comparison. Losing the Academy Award to John Wayne is one of the most ridiculous decisions ever made by the Academy of Motion Picture Arts and Sciences. Director Schlessinger has a deft hand with his production, but this film has a grungy underbelly that leaves a bad taste in the mouth of the viewer. Worth seeing for Hoffman's performance alone. Question: is it a positive review?
[EX A]: yes

[EX Q]: Review: I had the privilege of watching "Holly" at the Edinburgh Film Festival last week. What a powerful and moving story! Holly is a 12 yr old Vietnamese girl who is sold into prostitution by her own family and living in a brothel in Cambodia. Patrick (an American) comes into Holly's life and decides he wants to help her. When Holly is sold again, Patrick desperately searches for her. We follow they're difficult journey through Cambodia and hope for their reunion.Holly is one of millions of children who are sold and trafficked every day. The movie portrays this difficult issue without crossing the line. I walked away wanting to know more about the issue of child trafficking and asking how can I help? This movie should be seen by everyone because it is a beautiful story and it exposes an issue that we should no longer ignore. Question: is it a negative review?
