I liked this movie for being very deep and complicated in story, while not being so much unclear. It just explains us realistic and possible real life complicated situations. Emotional, funny, realistic, serious, religious, moral, teaching, but negative. Also interesting insight into Korean culture and behavior. The only thing that makes this movie bad is that it is too negative, and especially negative ending. Teaches us about instability of life, greed, desperation, survival, crime. Worth an oscar at least because of its depth or because of seriousness of topics or lessons. Not good to watch for those sensitive to scary and difficult realistic situations like getting hurt, imprisoned, etc.
