Part of this might just be account switching issues though. If I’m watching for myself I can usually find what I want quickly. The problem comes when I’m trying to browse with my wife to find something we can both live with. At best it gives the my preferences and the Union of me + wife’s preferences (and vice versa on her account.) But what we’d really want is a separate recommendation feed that shows the intercept of me + wife’s preferences.

But most people are lazy and won’t account switch for different contexts like that anyway, so there’s just no way they can keep the profile data as clean as it needs to be for a television.
