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: Many critics have felt offended that R.W. Fassbinder has portrayed both protagonist Wilkie and the Nazis in this movie in a human-like manner. Connoisseurs of other Fassbinder films, however, will realize that "Lili Marleen" (1981) belongs to Fassbinder's "women movies" like "The Marriage of Maria Braun" (1979) and "Lola" (1981). Fassbinder was convinced that "stories can be told much better with women than with men", because, according to Fassbinder, while men usually fulfill their determined roles in society, "women are capable of thinking in a dialectic manner". Dialectics, however, means that there is not only a thesis and its antithesis like usually in our black-and-white world, but a synthesis where the oppositions coincide. Moreover, dialectic means that because of the third instance of synthesis the absolute opposition of the difference between thesis and antithesis is abolished. Concretely speaking: Starting from a dialect point of view and portraying the fascist state, the underground fighters must necessarily use the basic means like the rulers do, and between offenders and victims there is thus a chiastic relation, so that every offender is also victim and every victim is also offender. Fassbinder has illustrated this abstract scheme, that transcends classical logic, in his play "The City, the Garbage and the Death" (1975) which was filmed by Daniel Schmid under the title "Shadow of Angels" (1976).Therefore, approaching an a priori controversial topic like Nazi Germany, in a dialectic manner, the depiction of this time in the form of a movie gets even more controversial, especially for people who cannot or do not want to see that our recognition of the world is by far not exhausted with a primitive light-switch schema, but needs the third instance of synthesis as controlling instance of its opposite members thesis and antithesis. The mutual relationship between offenders and victims has to scrutinized, since it is simply not true that the offenders are the bad ones and the victims the good ones. In a synthetic viewpoint, the bad ones participate on the goodness as the good ones participate on the badness. They are mutually related. In a world-view based on classical logic, a relation between good and bad cannot even been established, and in an ethics based on this insufficient system of logic, the bad conscience of the survivors of Nazi Germany, feeling (illogically enough) responsible for the deeds of their ancestors, exclude the possibility of a relationship between the two extremes and thus a synthesis in the form a new evaluation based on this relationship as well. From Fassbinder's dialectic viewpoint, it follows that neither Lili Marleen nor Lola nor Maria Braun can be condemned for their "misuse" of the ruling system for their private purposes, because they don't misuse them, they just use them. In the opposite, since victims must repeat the actions of the offenders as the offenders must repeat the actions of the victims, because "good" and "bad" are no longer simple mirror images of one another like in two-valued logic, their strategies are legitimated by the chiastic structure of a logic that describes our world, that is not black and white at all, much better than a black-and-white logic.

Review: Pleasant story of the community of Pimlico in London who, after an unexploded WW2 bomb explodes, find a Royal Charter stating that the area they live in forms part of Burgundy.This movie works because it appeals to the fantasy a lot of us have about making up our own rules and not having to listen to THEM. A solid cast of British stalwarts, especially Stanley Holloway, makes this more believable.There are some very nice moments in the film, such as when the people have ran out of supplies and other Londoners on the other side of the barricade start throwing food and other things over to them.Even though you always knew Pimlico would become part of the UK again, the people of PImlico and as a consequence the viewer doesn't mind when this happens, leaving a nice happy feeling.It's amazing to think that these low budget movies from a small studio in London still remain so popular over fifty years later. The producers must have got something right. Question: is it a positive review?
