Since I started using MovieLens.org and let it learn what I like, I get pretty decent recommendations. I am also adding tags after I watch the movie. Recommendations has to be highly personal. Thumbs up/down is not enough. And global rankings are totally useless for me. I rarely like top-rated movies. I hope no corporation buys them and rewrites/destroys the system as it is common with all acquisitions because the way it works now is perfect. They should open-source it to preserve it and help the society. I pay for Netflix but I rarely use it due to DRM (a bit complicated in Kodi) and lack of movies (too many shows).
