I thought this year's WME effort was aaaaaverage. So you went and survival-skied down some bulletproof ice in some obscure location... who cares? Quite a bit of the skiing was pretty normal skiers skiing very normal terrain that was somehow special just because it was somewhere really weird. All the good freestyle footage was cutting-room-floor leftovers from PBP.
But definitely Motive by Splice Productions. Especially the bit where that little golem shouts SPLICE LIFE at the end of the edit that came before it.
