It seems to me that Netflix used to have better recommendations. It's unclear why/how/when it went bad, my suspicion is that they changed their metric and it's having bad side effects, or their old models didn't scale as their user base grew quickly.

I've built deep learning recommendation systems in production for clients with millions of users and it's sometimes surprisingly difficult to beat the "most trending <products>" baseline if all you care about is views/purchases. It will in the short term to meet business goals, but it hurts the user experience over time and will inevitably increase churn.

I wonder if it coincides with their change to a simple thumbs up/thumbs down rating system. I never rate titles anymore unless it's really good, or really bad. The in between I just can't pick.
