CHINATOWN is one of my all time favorite films also. Definitely my favorite "film noir" even though it is in Technicolor and made in the mid 1970s. I agree that everything about it is perfect, from the simple beginning with a P.I. working on a routine cheating husband case to the ever building conspiracy. And it's about the town we live in, Los Angeles, and its sordid history. I thought Faye Dunaway deserved the Oscar but the Academy voters thought differently. She did win an Oscar the very next year for NETWORK but I thought that should have been at least her second if not third with BONNIE AND CLYDE being her first. As for the score, I get goosebumps the second the opening chords are struck. It is so haunting and you just know you are if for a tragic tale.
