I've created a list of Edgar Wallace movies; https://thetvdb.com/lists/15993 Since Themoviedb has rather strict rules for creating collections. Could you get lists (either only official or any custom) and make collections from those? I think that could be helpful. I get that this would create all sorts of Collections, which may not be desired, so only accepting official ones could be better. Pulp Fiction for example is also in what I'd call private lists; https://thetvdb.co
