Longest i’ve ever gotten out of a pair was around 1600km on a pair of triumph 18. Admittedly those were used a bit too long, although having a rotation helped. At the end i just used them for occasional shorter slow runs.
On average l try to get at least 1000km+ out of each pair.
But ghosts are definitely known for good durability
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
