Maquilapolis

This film was very effectively concieved and executed. The filmaker's minimal presence seems almost a perfect balance for this story; the women of the collective themselves tell the entire story, present, narrate and explicate their struggle while the filmakers simply enable this story to be told. The production value, seamlessness, and overall effectiveness of the story telling is no doubt aided by this collaboration.
In this sense, this peice seems to find, as John mentioned, the balance between filmaker and filmed in the documentary situation that stranger with a camera spoke to and grappled with (and, questionably, found). The story of the piece is also rife with collaborative elements on many levels: the local attorney helping the collective, the members of the community helping each other, the women helping their children to achieve class mobility, the environmentalists' collaboration with the collective and its movment, and even the whole movement helping the river to be bright.
It is heartening to see these collaborations in the film leading to successes. The collective certainly seems undaunted, with high aspirations, on the path to many victorys. The successes of the film itself, those of it's impact, too, are likely numerous. As the quote from the case describes Maquilapolis, it is "A stirring work that'll provoke genuine outrage." Perhaps though, it can also provoke a certain awareness in its audience that leads to mindful action on an individual yet global level.
