Not as dark or heart-wrenching as it could've, and perhaps should've, been. With that noted, <em>'Eight Below'</em> - a remake of 1983's <em>'Antarctica'</em> - is still a fairly decent survival drama. The cast certainly elevate my feelings towards the film, with Paul Walker impressing in the lead role; it comes across as if he actually does have a bond with the dogs, which is obviously key. It's very much Walker's show, but Bruce Greenwood, Jason Biggs and Moon Bloodgood all add small but welcomed things with their characters. The dogs themselves are great and do a lot of good work…
