The photography of this adventure alone is worth a look see, and following the crew as they seemingly retrace Shackleton's voyage is absorbing, but this is a different kind of documentary. The film is interesting given the subject matter and goal of recording global warming effects on Antarctica. The filmmaker's technique however, of employing a fully orchestrated score to overly dramatize points being made can be a bit unnecessary. It's good composition, and there's no doubting the filmmaker's sincerity, but the visuals themselves are staggering enough without enhancement. Donald Sutherland's narration can also border on the overly dramatic, as can the slightly preachy writing. Still overall, the film documents a rare achievement and adventure. Additionally, there is some great bonus footage (but one non-English segment with French subtitles), and brief photo gallery.
