This is the biggest problem. I have different profiles for family members. Some members get so many more good new shows that don't appear in my profile.

Their library isn’t that big. If it wasn’t suggested to you and you could actually just look through their library you’d have found those titles. Disney+, Hulu, HBO, and other streaming services do this and it works fine even when they also offer suggestions.

I used to be able to find things to watch on Netflix when they had publicly visible reviews. Then they removed that, presumably to hock their less than stellar original content. They optimize to try and show you as much crap as possible, which is the real reason you can't find good stuff on your own -- it's not the lack of some personalized algorithmic magic that's responsible here.
