By far, this movie leaves every other Himalayan climbing movie in the dust. The images of the climbing teams were so realistic and depicted so beautifully that it left me in awe. Having been around tall mountains, I can safely say that the mountain scenes was very well done.
The movie also captured the 'tank' personality of the main character Captain Um. He is a driven man, and the story reveals how much that impacts his life and work. It also smoothly depicts the age/stature value that is practices so clearly by Koreans. The lead actor did a tremendous job of getting Captain Um's character, his mannerisms and attitude.
Of course the movie is emotional, I had to see it in two sittings. That emotional aspect of the film is what gives it its human quality - after all the whole expedition to rescue a dead teammate is very much a human reaction. I am very glad that the movie took in stride the god times, as well as the very sad times in a very realistic way. I loved the scenery of South Korea as well, the movie blended these city scenes with the mountain scenes in a balanced way.
Fantastic movie! And yes, bring the tissues.
