it's mostly a matter of taste.

i would not see Citizen Kane a second time, whatever the "experts" say about it; Vertigo is far better.

one of the best movies i've seen and seen again is Bergman's Cries and Whispers. Everything about it is excellent and it's filmed as a suite of work of art tableaux.
