[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: From the awful death scenes to guns that fire without making sounds to a character called the Fiend. It's all tiresome, slow moving, unimaginative drivel. It was OK seeing the guy with the cape and the hunchback lurking around. Visually it was creepy and probably occupied the moviegoer of the time, but even in 1936 one would think that there would have been a little more imagination and verisimilitude to even a film like this. I just kept waiting for something to happen of any importance as people stood around making speeches and acting like they were posing at an office picnic. And then there are those bullets as a previous commentator mentioned. Perhaps the best clue would have been to search for a water spot on someone's pants pocket. Question: is it a positive review?
[EX A]: no

[EX Q]: Review: Home Room really surprised me. In comparison to other movies that were written regarding Columbine high school this one is the best. Home room does not show the school shooting but rather the aftermath and the effects of the community and the town. The movie focus' on two opposite characters., Alecia(Busy Phillips) and Deanna(Erika Christensen). Alecia is an outcast who witnessed the entire shooting. She seems to show no emotion about it. Deanna is a popular girl and the only surviving victim. Alecia is forced to visit Deanna at the hospital in order to graduate. Meanwhile the police are investigating Alecia as she might have known the shooting was going to happen. Alecia and Deanna are very different and do not get along at first. Eventually they develop a mutual understanding for one another and become friends. (very much in the style of the breakfast club). Home Room Beautifully shows the power of closeness and turmoil after a school shooting. I would recommend this film to anyone and everyone. Question: is it a positive review?
[EX A]:
yes
