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?

Review: There are people claiming this is another "bad language" ultra violence Mexican movie. They are right, but more than that this film is a call to create awareness of what we have become. The awful truth hurts, or bores when you already have accepted the paradigm of living the third world as the only possible goal. One of the most important things of "Cero y van cuatro" is the open invitation to profound reflexion over our current identity. Is that what we all are? Is that all that we want to be? I am abroad and I realized how spoiled is the Mexican society when the Tlahuac Incident came to light. I still cannot understand viewers witnessing a mass broadcasted murder. I nearly puked when I saw some of the images. It was not Irak or Rwanda, just a tiny village near Mexico City when rampage was carried out with the indulgence of media and government. The recreation of a similar situation in this film shocked me deeply. The other stories were good portraying other situations of corruption, dishonesty, betrayal and violence, but I consider "Tamales de Chivo" the best one.The movie is deeper than some "cabrón" and "pendejo" screams. Those are meaningless compared with the actions of the people. With a few exceptions they are all perfect examples of human rubbish. Just like in real life honesty is becoming more the exception than the rule in our country. Moreover, honesty is only rewarded miraculously. Question: is it a positive review?
yes

Review: This movie was just down right bad. I love war movies and can normally come away from most movies and find something that I liked,but this was not one of them. This movie lacked substance and intensity.OK I get it, the Finns put up one hell of a fight and thats great, but the story is poorly told. You don't have any real connection with any of the characters and there's no real story line to follow. You just go from one random scene to another, nothing flows to form the story that is trying to be conveyed. If you want a war movie that will keep you riveted, and amazingly enough without battles scenes, then I would suggest "Downfall" (WWII German film). Or if you prefer a great story line and a lot of action then I would suggest "Brotherhood of War" (Korean war/Korean film). These two movies will not let you down as Winter War will.
