Farmingville is a good documentary that seems to be very fair and truthful in how it tells the story of two Mexican day labourers (illegal immigrant workers) who were victims of assault and attempted murder, and the town that they lived in, the titular Farmingville in New York state.
The story could be told in a more interesting way, particularly some of the visual elements of the film and stock footage (though I'm sure they just used whatever they had available to them) but it does a great job when it comes to presenting the facts and opinions of those involved. They don't focus too much on one side of the story and in fact by doing so they end up making a great statement about how everyone needs to step outside their own shoes and consider how things are seen by people on the other side of the fence.
