A lot I can write about it, but I don't want to spoil anything. The authenticity...the SOUND, how you watched these poor soldiers struggle, how they regarded each other... No wonder it's won audience favorite for every film festival it was in. (I also love how no big Name Actor was in it. Makes the experience that much more real. It wouldn't have been the same if say, it was Tom Cruise struggling out there in the snow, trying to sneak a full 30 seconds to pray.)
Go and see. If it's not a contender for Best Picture, Hollywood is well...Hollywood. So it won't. But it SHOULD.
Full, full marks.
