it is strange to define it. it is a homage to pioneers of geographic adventure, a history lesson, an inspired trip at the true essence of adventure, not ignoring the portrait of noble heroism ,but giving a realistic story . sure, using the precise expectations about artistic virtues, it is far to be a great movie. but it is a decent one. and this fact remains a significant good point. or,maybe, a reasonable portrait of brave men and theirs fight against nature.
