Missing context

Although this was a brilliantly photographed and engrossing documentary, I think Sebastian Copeland should have elaborated (if only slightly) on the circumstances of the Peary expedition that he was commemorating. There is considerable debate -- and a lack of evidentiary proof -- as to whether Peary actually arrived at the North Pole. While some historians consider his integrity suspect, the most likely culprit (if he did in fact not reach the Pole) was Peary's lack of navigational skills and absence of skilled navigators on his team.

Here are some interesting background articles:

Copeland didn't need to make a big deal about it, but he should have referred to the controversy as it's by no means an accepted truth that Peary made it to the pole.
