Review: not your typical vamp story, not bram stoker or anne rice here. a truly original vampyre story. these vampyres are genetic mutants who the sunlight don't bother. they are pure evil to. the film is not perfect. many of the actors are clearly amateurs. the two leads who play van helsing and rally the vampyre chick are pretty good though. the film is intensely violent which may disturb some people. also it is loaded with scientific detail that many will find hard to understand and may get bored with. i was sold on the clever storyline and the couple good performances. no telling how successful this film could be if they had a bigger budget and it got mass distribution Question: is it a negative review?
yes

Review: Well, I have to say, this movie was so bad that I would have walked out if i didn't have to review it for work. ANd the worst part is, I wanted to see it so badly that I drove all over the city, paid $10 parking two times because the newspaper listings were wrong. Vince Vaughn plays the guy he always does -- the only time I've seen him play someone else was in that movie with John Travolta. Anyways, the plot has potential -- it sounded great in the preview, but it is filled with totally ridiculous, predictable, weak plot turn points. And I was hoping that this would be one Christmas movie where Christmas DIDN"t have to be saved, and that Santa didn't need a replacdmetn, but nope. The only cool part was the sleigh rides, and the little bladck kid was the best character. I'm sure this movie would be great for young kids, but for adults it's so lame that it's chore to sit through. Question: is it a negative review?
yes

Review: Faithful to the work of Pearl S. Buck whose years spent in China as a child of Missionary parents that provided her with deep insights into the Chinese culture and its philosophy, this film adaptation is brilliantly done, both in technically artistry and acting.Wang Lung is a humble farmer grateful for the basics of life: to survive off of his land and to be newly wed to Olan, a servant to a rich and powerful family in the village area. Despite Wang Lung and Olan's best efforts to farm the land, raise kids, and build savings and wealth, a famine threatens to wipe out everything they have worked for. Choosing not to sell their land, a traditional Asian belief, they instead journey to a major city to wait out the famine. While in the city, they are reduced to begging and being just one of hundreds of other unfortunate homeless families. Although not a looter, Olan gets caught up in a mob looting at a rich man's house. She's summarily rounded up for execution by the army, but is saved at the last minute. Her good fortune, however, is that she found valuable jewels at the looting site that affords her and her family the opportunity to return to their farm to start over again. The newly found wealth transforms Wang Lung. He becomes selfish, self-centered and takes credit for the find. He becomes a very rich farmer but that only makes matters worse as he increasingly becomes more unappreciative, arrogant and difficult to reason with. He loses touch with the basic things in life that money can't buy: loyalty, commitment, trust, fairness and honesty. As punishment, nature once again turns the table on Wang Lung by sending a plague of locust to destroy everything he has. Brought to his knees, Wang Lung enlists the aid of all friends, former friends, workers, and family. With all that help, he succeeds in saving the farm. From that experience, he once again returns to humbleness and an appreciation for the basics in life. Question: is it a positive review?

yes
