I don’t think that works well for movies and tv shows because there is way less datapoints than music (they are way longer, meaning we don’t consume that many films/episodes). A song is also generally more focused, you generally have one tempo, level of energy, and limited instruments. A move on the other hand is a mix of so many art forms. If you only rely on what your cohort voted for you’re missing so much information to make an actual good recommendation.

Netflix system seems to work for their goal, which is to increase revenue, but it’s not a great system for the user satisfaction
