The only reason to spend money on this is if you want a good laugh, or an example to show film students of what not to do. It's so horrible we could not watch beyond the first episode. The narrator sounds like the robot who calls you from the drug store to tell you your prescription is filled, and he mispronounces words so that their meaning is distorted. So bad it's funny. The sound is terrible---sounds like they recorded it with a toy mike. The footage keeps repeating itself. I honestly can't understand why anyone would put the work into producing a 7.5-hour documentary and think that this is acceptable. High school students could do better. There are much better documentaries out there, folks. Run from this one. It's a giant waste of your time.
