Black Gold is a documentary about the coffee trade. It's conclusions are not perhaps the most astonishing in the world — the coffee industry makes lots of money while most of the producers, particularly in Ethiopia, are not doing nearly as well. Still, perhaps, these are points that need making again and again. The role of the WTO and the trade policies of the first world are, perhaps, less obvious.

The documentary seems to have a got a new lease of life, more or less entirely due to Michael Moore. Unlike his work, or Supersize Me, Black Gold lacks a comedy turn to keep the interest going although the main protagonist, Tadesse Meskela, is engaging and charismatic.

The music and cinematography are both wonderful, though, making this a clear and compelling film. Well worth a look.
