Blue Alchemy: Stories of Indigo

This is an informative documentary and has some very interesting video footage, but the last 20-30 minutes are repetitive and don't add to the story being told. The film begins by showing the complex process that is involved in creating blue dye from green leaves. The process differs in different parts of the world, but the resulting dye is indigo. This first part of the film is quite fascinating. Unfortunately, once the director has finished showing the segments about indigo production in India, Pakistan, Africa, Mexico, etc., she then continues in the same vein with two additional segments - one on India and one on Mexico - segments that don't add anything new to the information already imparted by the first segments on India and Mexico. These last segments seem to have been added as an afterthought or perhaps as filler. The film would far be more effective without the last segments.
