I'm not big on "Rewatchables", there are probably fewer than 10 films that I've re-watched from start to finish.
Interestingly, nearly all the films mentioned so far are American.
But rewatchables are certainly a thing....many videos, podcasts (The Ringer has a Rewatchable category), and rankings.
a recent poll https://www.ranker.com/crowdranked-list/what-movies-can-you-watch-over-and-over-again--v1
Of that ranking, I've rewatched six of the top 10.
