I must say that Daniel Day Lewis deserved that Oscar.  He did a marvelous job of being simultaneously charismatic and repellant. The movie was well scripted and filmed, and I found the score particularly interesting. But, MAN was that a dark dark DARK story. 

The popularity of "Jaws" aside, I think his performance in "All That Jazz" was really his best.  Who knew he could dance and sing as well as play a drugging megalomaniacal SOB!?!
