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?
yes

Review: Other than Susan Hayward's wooden delivery throughout this film it was as good as any biblical film made. Henry King handles this film with the respect of an epic in all of the small scenes, and Peck is, as always, impeccable. The stirring Alfred Newman sound score, with the stirring twenty-third psalm is unforgettable even after these many years. The scene with Goliath is a bit on the hokey side, but not all that badly done for the era in which this film was made. This goes well alongside the lesser bible epics of the day, "The Song of Ruth" and "Esther and the King." It is worth watching, and Raymond Massy is excellent as the prophet Nathan. The film is rounded out by the always fine James Robertson Justice as Abishai and Jayne Meadows as Michol, David's estranged first wife. Question: is it a negative review?
no

Review: Mt little sister and I are self-proclaimed horror movie buffs. We have seen just about EVERYTHING, especially zombie flicks. Now, we have seen a lot of good zombie movies, and a lot of bad ones. This BY FAR is the WORST movie I have ever seen in my entire life. Not only was the acting horrible, but the special effects, graphics and ever "zombie" make-up was the worst I have seen. If you can even call it make-up ( black eye shadow around the eyes) This is totally proof that you should never judge a book by it's cover. Cause the cover to the movie is the only sweet thing about. do your selves a favor and DO NOT WATCH THIS MOVIE!!!!!!!!!!!!!!!!!! I was so adamant about this movie I went as far as putting a sticky note on the inside of the movie before i returned it to movie saying "This movie sucks, don't waste your time, return NOW" hahahhaa I don't want anyone else to waste a good movie night on this POS movie! i don't even know how it got the ratings that it did, t should be in the negative Question: is it a negative review?

yes
