The flick begins by mentioning that polar bears resulted from brown bears (grizzly bears) migrating to the Arctic and adapting to that environment, a theory that comports with accepted thinking. Unfortunately, the idea that polar bears might migrate south and re-adapt to a different climate totally escapes the biased story-line developer. Never have I heard such misguided and erroneous information about anthropogenic global warming and the plight of a subspecies. That said, the photography was exceptionally good in part. While providing a glimpse into the life of polar bears, the focus on their supposed plight became tedious and boring. Minor and limited photography of other wildlife and sea creatures was of interest if you can forget the overall bias. I have to wonder how the story-line might be altered if presented from the point of view of the seal - a primary source of food for the bear as presented by the flick. I also continue to ask myself the question, "Does Ms. Streep have the slightest clue why Greenland is so named when 80% is covered in ice today?". I certainly enjoyed much of the photography, though the film dragged at times and the bias caused attention to drag.
