Pretty much all criterion / filmstruck (rip) and so pre-canonized. Still, major discoveries for this viewer.
Some notable re-discoveries or re-appreciations:
Woman Under the Influence: the peak of Cassavetes unique approach to story and performance
North by Northwest: never would have thought this would edge out the stellar Jimmy Stewart Hitchcocks from the same decade, but yeah, this is my new favorite Hitch
Rio Bravo: my favorite Western, my favorite Hawks, possibly my choice for greatest film of all time
