We love this idea and are formulating some plans around collaboration in general.Garrett commented
This still isn't a thing after 6-7 years?
We have an Export of your watchlist in Settings. If IMDb supports importing it, this should work. Full sync isn’t possible without a free, open API which they don’t have (and neither do we, yet).Garrett commented
What about if we at least enter it into IMDB as watched or add to watchlist it was just auto-sync'd to Letterboxd, or the opposite only? Then I could primarily just use one but it would then update the other.
My reasoning is IMDB's inclusion on TV and Netflix series, I want to have them all in one place but I love the interface of Letterboxd so much more.
