What movie rating system do you trust?

4. Mostly, this DU group/forum

But I have a related question: has anyone ever encountered a good "referral" system/app, that one could customize the input manually--like, you create a category, then select a bunch of your favorite films/shows, and it gives a list of suggested titles based on criteria you can select and weight, whether it's genre, actor(s), director, etc. Obviously all of the streaming services offer some variation of this, but I've never seen one that the user can customize.

There are so many films/shows that the only way I discover them is randomly, in spite of the numerous watching venues I use and the amount of watching I do--no current algorithm that suggests titles for me has it refined in the way that would be most accurate and useful for me, so it ends up being mostly a crap shoot.

This recently came to my attention when I randomly discovered the film "Nightmare Alley" -- a film that perfectly fits my criteria, and yet, I'd never even heard of it! I imagine there's a whole treasure trove of stuff like that, buried on Netflix, Hulu and Prime. How to discover them readily, though?

Know what I mean? If it doesn't exist, here's a good idea for an app developer.
