What is the difference? On the surface, it doesn't seem like music recommendation should be a very different problem from movie recommendation.
Unrelated to this: I find the comparison between Netflix and Spotify interesting in general. Why do I get (pretty much) all the music there is on Spotify, but I cannot subscribe to a movie / tv streaming service that lets me access all the content for a flat fee? As a consumer, I would much rather have the choice between three well polished streaming platforms that all offer the same content compared to the current situation where you have a fractured catalogue on platforms of wildly varying technical quality (looking at you, Amazon..).
Browsing Netflix for 2 hours only to watch nothing is so common it's memed after all..
> you need the right people involved
Even then it's tough. The Mandalorian was great. Then The Book of Boba Fett came out and was not only a disaster, but also made the entire two seasons of The Mandalorian pointless. Similar to season 8 of Game of Thrones killing the entire show, because who can recommend a show that sets up the central expectation in season one that is so horribly resolved in the very last season. It's now a show I'd recommend to my enemy rather than my friend. TV is tough. And I don't think streaming is kind to shows that don't nail every season. This is content that is part of a catalog. It's not something on NBC on a Thursday night. Syndication isn't just a nice windfall. It's the entire point now.
