the blog posts series on rec system is interesting. But when I watch Netflix I still run into simple issues. can you please take care of some basics first, such as if I press 'thumbs down' then Netflix would never recommend that title again or similar to such titles.
They can't do that. Netflix now has very little content since all the big players have pulled out and started their own streaming services. Netflix has to recommend what it has: old movies, subpar TV shows, things you don't like, Netflix-produced content.
