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?

A: yes

Q: Review: I drove from Sacramento to San Francisco (and back) to see this movie premiere--and really glad I did. As a big movie fan and a life-long Northern Californian, I was surprised how many Oscar-winning films have been made in the Bay Area. As a fashion designer who really wants to stay in the Bay Area as opposed to going to LA, George Lucas' comments about persistence, community and having a vision really resonated with me. Hey, if he and all the other filmmakers can make it in SF, so can other artists. Would recommend this film Question: is it a negative review?

A: no

Q: Review: Worst movie on earth. I don't even know where to begin but I hope I can save another person from punishing themselves with this movie. When it comes to acting and lighting, this movie is similar to a bad porno without the sex. The actors are some of the worst I've ever seen, and couldn't have been worse even if they were trying to make a complete mockery of this movie. The movie must have had a record breaking low budget which I'm sure was wasted almost solely on the movie's cover. This movie has now become a running joke with friends of mine and has become the standard for comparing other garbage movies. I would like to point of that no other movie even begins to compare. I feel personally responsible for suggesting a friend and me watch this movie and am surprised she still considers me a friend after the torment I put us through. Don't see this movie!

no
