"Blind Shaft" is a good/great film about two con men. One of the con men is more vicious than the other, and has lost all feelings for other human beings. The other less-vicious con man still has some pangs of conscience, but both will do whatever it takes to survive.
This is like a small "Goodfellas" in that the two crooks, and the mine bosses they work for, are corrupt, and have no qualms about criminally exploited those around them. They live in a world of crime, and act accordingly. The Chinese street scenes ring with authenticity, no Westerners are present, this the China that hundreds of millions of Chinese see every day - poor, impoverished, corrupt, desperate, where the Communist party has long since abandoned Communism, and Socialism is just an empty slogan.
Nevertheless, there are good, compassionate people in this cynical environment. This film is really about one man's "redemption", the less negative of the two con man, and his realization that his destructive path in life is wrong. I'm writing cryptically because I don't want to spoil what the con is, I recommend this film highly, and I think it will play just as well on the small screen as on the large. See it on the big screen or DVD, but just see it!
