You make a good distinction. In my opinion this question can be answered in two ways:

• A movie that holds up being just as good on a rewatch.

• Movies where you either pick up on clues/details on further rewatches once you know the full movie. Or that are just so dense/layered that you just can’t catch everyrhing the first time you watch it

Doesn’t matter how often you see scenes like ride of the rohirrim, they remain just as epic as they were the first time.
