PROBLEM: Review: I enjoyed this movie,and after watching it,it made me wonder just how many 'Caitlin Rose's' exist in the world.How many other girls have been subjected to this sort of sexual abuse,and torment by classmates and have been too frightened to open their mouth about it? Just how threatening and cruel can teenagers be towards one another,because as this film demonstrates,who's right is not foremost important,its who is popular,and feared which manipulates the minds of youths,and influences them to allow this sort of immorality to happen.Tiffani Amber Thiessen gives a powerful performance as the rape victim,and Brian Austin Green is convincing as the guy torn between the girl he thought he loved,and his best friend.This is the kind of film that doesn't get the exposure it deserves.Remarkable,and brilliant,too good to be just a film made for TV. Question: is it a positive review?

SOLUTION: yes

PROBLEM: Review: In Iran, women are not admitted to soccer games. Officially it's because they are to be spared from the vulgar language and behavior of the male audience. But of course it is about sexism. Women are lower forms of human beings.Some brave girls oppose this and try to get into the stadium by using different tricks. They are caught by soldiers and hold in a kind of cage, until the police will come and pick them up.Despite the insane situation, this is a film with lots of humor. It's also encouraging to see how people always find different ways of fighting oppression. You'll get touched at the same time as you have lots of laughs. Good job by director Jafar Panahi. This is in many ways a heroic comedy. Question: is it a negative review?

SOLUTION: no

PROBLEM: Review: This docu-drama is what you would expect from Richard Attenborough, the man who gave us "Gandhi": beautifully photographed, compellingly casted, well written in the measured, literate manner that Hollywood discarded in the 30's, and scrupulously accurate. It stands out as a genre film, excelling in its portrayal of native American (or, more appropriately for its Canadian setting, "First Nations") culture and standing with "Black Robe" as a wonderfully photographed piece of Canoe Country and its culture (here, circa 1934). This idyllic portrait derives drama from its subject: Archie "Grey Owl" Belaney, a Scot raised in Hastings (England) by maiden aunts who became so obsessed with the "red indian" tales of his childhood that he went to Canada, disappeared into the woods, and became a trapper and adopted son of an Ojibway band. He was a vain man with a habit of marrying and abandoningIndian brides, none of whom seem to have thought less of him for it, for he was also an extraordinarily charming and picaresque character. One of his wives (one smarter than he, by most accounts) propelled him into fame as a writer and early advocate for protecting the wild country of the North, and this forms the focus of Attenborough's tale. The chemistry between Brosnan and Annie Galipeau (as Grey Owl's wife Pony) is engaging and, if not firey, is nonetheless quite touching. A good film when you need some time from the madding crowd.
