I wonder if there's space for a proper, quality recommendation engine for Netflix. In my books, it would do exactly what you described here, plus provide way for user to input persistent constraints (e.g. "Don't show me movies from 'Horror' genre") and queries (e.g. "genre: sci-fi, after: 2010").

How could it work with Netflix without their explicit support? For the movie database, I assume there's some data source somewhere that lists all the movies and series Netflix currently has in any given region. As for ingesting watching history, it could parse Content Interaction History exported from Netflix via their GDPR Subject Access Request flow. Sure, they have up to 30 days to process such request, but I'd happily accept a recommendation system I have to manually update every month, over the disaster Netflix has been offering to its users.
