Scorsese really gets it, what it means to be a cinephile, to understand a movie for more than it's surface, take in the images and meaning and apply it to other things. His commentary here on "On the Waterfront" and "East of Eden", Kazan's best films, is both insightful and poignant.
Scorsese suddenly seems like an appropriate disciple of Kazan's work, especially crystallised when he talks about the conflict we are supposed to feel about Kazan's characters. Mainly focuses on Waterfront, Eden and America. As with these things I kind of wish each movie had its own episode. Passionate textual analysis, not enough of it.
