Not dissimilar to what Steam implemented, which is basically Bollinger bands for ratings.
If I'm trying to pick a movie, I don't care what its score for rewatching is, I care about what its score is for watching it the first time.
And once I've watched a movie, I don't care about whether other people say I should watch it again, I care about whether I want to watch it again.
A movie is different from buying a board game. If I'm shelling out $50 for a game, I'll want to know if it's still fun the twentieth time I play. But that isn't a consideration when picking a new movie to watch, the experience may be worth it even if I never watch it again. And ditto with books. I'm probably not going to read that 800-page book again, but that shouldn't stop me reading it once.
It's also a genre independent quality metric. That's not to be underplayed. Some examples of films that successfully passed it for me: Casablanca; Portrait of a Lady on Fire; Hereditary; Under the Skin; My Neighbor Totoro; The Fifth Element. I'm pretty sure most people would agree at least half of these movies are good.
It turns out most of the things I consider worth revisiting at least once are also things other people would consider that way. So for me a Rewatchability rating is a positive signal.
These movies are some of the most impactful that I have ever seen, but by no means would I rate them highly rewatchable. They are gut wrenching, and some people can only stand to watch them once, few want to rewatch them, but they are also incredible.
I also gain a lot from a rewatchable piece of content, but you might be shorting yourself by always watching things designed to tickle the dopamine receptors.

Now this I just do not understand. Things designed to be good on primarily the first watch, and allowed to degrade on future experiences, seem much worse for this.
I think we are coming from different feelings about rewatchability.
If you asked me to rate movies as to their artistic merit, their excellence as films, I would say that those all fall into “instant classic” territory. However, I would not want to rewatch them in the same way that I might want to rewatch a Coen brothers film, for example.
That's fine by me, of course. The more signals I have, the better my decision can be made on what to watch next on average.
For example, I just watched the Gorge. I enjoyed it, but I wouldn't rewatch it. I don't think it necessarily deserves a bad grade though.
Now, some great movies I wouldn't rewatch. La vita e bella and grave of the firefly are beautiful, I just cannot rewatch them.
It's definitely a limited metric tho.

One of the main frustrations I have with Goodreads is how limited the API is nowadays, and how there appear to be no measures against brigading and other campaigns. One of the core issues with ratings services.
Personally I'm hoping Open Library by the Internet Archive grows more in popularity, given how most websites come and go:
