I liked this movie for having so much about survival and adventure. Meaning we could see airplanes, migs, avalanches, storms, wolves, criminals...which is all fun. Also very real, if not for the scifi or bit extreme reality part, then at least for realistic relationships, and devices. Wolf not scenting humans from the close up was a bit fake, and too sudden and extreme storm appearing so quickly without good and slow enough intro and details. But considering that it at least has better ending, and not so annoying...but enough amount of action and talking. Positive ending. Bit negative but realistic, better than positive but fake.
