I watch it at least once a year-- around the holidays-- and I keep thinking "one day I'll get tired of it." So far, it's not even close. It's more like a beautiful piece of music-- I will never, ever, get tired of listening to Mozart or classic rock. It's a film with intricate rhythms, themes and sub-themes, crescendos, and counter-point (the intercut Catholic mass and the brutal hits).
One of my grandmother's rules, passed along to my mother, and to me: any time you use tomato paste you need to add a bit of sugar. Tomato paste is bitter.
And absolutely right, Jim, it's "gravy." We never called it "sauce." And "macaroni" not "pasta."
