I found this series to be informative and balanced, explaining both the perspectives of the natives and the westward-pushing Americans. Along the way, tidbits of knowledge filled in gaps of my own. For example. I never knew that Sacagawea had been stolen as a child and was reunited with her brother while guiding Lewis and Clark - a fact that saved the expedition. The series abounds with these factoids. I have one complaint, though. Couldn't the producers have found a flat part of New Zealand to film some of the scenes in? I cringe when I see scenes supposedly of lower Michigan, northwest Ohio or central Indiana, filmed in a mountainous area. Those locales might pass for Wyoming or North Carolina, but not the flat flat flat Midwest. Nonetheless, the series is entertaining and I recommend it.
