This movie offers awareness about the environmental impact on waterways of the jeans and leather industry. It's a good movie if you want to become aware of the impact of the clothing industry, but I wouldn't recommend it if you are an educated environmentalist.
There isn't a solid research behind the movie (or at least, it doesn't show). Unfortunately, there is a lack of real and sustainable solutions. The last part of the movie covers some new technology to make your jeans look used, but they are in no way "eco-friendly" solutions.
The movie offers great images and it makes people aware of the jeans and leather production impact on waterways, but no more. In terms of offering a more comprehensive portrait of the environmental impact of the clothing industry, I would recommend True Cost over that one.
